Video of my Talk at Digital Now

This is a video of my talk at the Digital Now conference in Orlando yesterday. There's a long intro by Don Dea, and then I speak (starting at index 05:14) about the Semantic Web and Twine.

Great Collective Intelligence Book; Includes a Chapter I Wrote

I highly recommend this new book on Collective Intelligence. It features chapters by a Who's Who of thinkers on Collective Intelligence, including a chapter by me about "Harnessing the Collective Intelligence of the World Wide Web."

Here is the full-text of my chapter, minus illustrations (the rest of the book is great and I suggest you buy it to have on your shelf. It's a big volume and worth the read):

 

Harnessing the collective intelligence

of the World-Wide Web

 

Nova Spivack[1]

 

Introduction

We are about to enter the third decade of the Web, sometimes referred to as “Web 3.0.” During this decade, the Web will evolve from a globally distributed fileserver into a globally distributed database. This shift will be enabled by a set of emerging technologies called The Semantic Web, which add a new layer of machine-understandable metadata about the meaning of information to the content of the Web.

The Semantic Web will catalyze a new era in collective intelligence. Individuals, groups, organizations and communities will be able to create, connect, find and share knowledge more intelligently and productively than ever before. Ultimately it will enable the Web itself, and all the people and applications that participate in it, to become more collectively intelligent.

Web 3.0—The Third Decade of the Web

The third-decade of the Web, “Web 3.0,” begins officially in 2010, but we are already entering the early stages of this transition today. To understand where the Web is headed it helps to zoom out to a larger historical context.

 The final decade of the PC-era (1980—1990) was largely concerned with innovation on the front-end of the personal computer: the desktop and user interface layer of the PC. The focus of this period was in making PC’s easier to use with innovations such as Microsoft Windows, the Macintosh user-interface, and more consistent user-interfaces and integration across applications.

 The first decade of the Web-era (“Web 1.0” from 1990 - 2000), was focused on the back-end of the Web: the core technologies and platforms of the Web such as HTML, HTTP, Web servers, search engines, commerce technologies, advertising technologies, and the basic architectures and business model of Web applications. This decade was mainly focused on the technology and infrastructure of the Web and most of the actual innovation dollars were spent on making things that only software developers could see.

 In contrast, the second decade of the Web (“Web 2.0” from 2000—2010) has been largely focused on the front-end of the Web. Much of the innovation has not been on actual technology but rather on design patterns and user-interfaces for improving the end-user experience of the Web. During this decade we have focused on paradigms such as

AJAX

, which is a set of technologies and design methodologies for making Web sites more visually appealing and interactive.

 Another big focus of Web 2.0 has been user-generated content, and in particular the practice of “tagging” content with subject tags. Tagging has in turn led to the concept of “folksonomies” in which taxonomies that organize data are evolved in a bottom-up fashion by a decentralized community of users.

 The coming third-decade of the Web (“Web 3.0” from 2010—2020) will shift the emphasis back to the back-end of the Web. This decade will be largely focused on upgrading the technical infrastructure and content of the Web, based on emerging technologies such as the Semantic Web. During this decade the primary push will be enriching the Web so that it can function more like a database.

 Today the Web is composed mainly of unstructured and semistructured data such as text files and Web pages. Keyword search engines are able to provide rudimentary search capabilities over this information, but only for the most simplistic queries. Compare current Web search to the more precise capabilities of queries against a database and the difference is immediately clear. The Web does not provide anything close to the search capabilities or precision of a database today. But that is about to change.

 The Semantic Web provides a way to enrich both unstructured and structured data so that it can be queried with the precision of a database. Essentially, it provides a way to tag any information with metadata that explains what it means—and this metadata can be understood by software applications, such as search engines or knowledge management applications. It’s important to note that The Semantic Web is not a new Web, it’s just a new layer of the Web we already have. The semantic metadata that comprises the knowledge of the Semantic Web won’t live in some new place—it lives right in the existing documents and data on the Web. The knowledge of the Semantic Web is encoded using special new markup languages such as RDF and OWL.

 This metadata is invisible to users (it doesn’t appear in Web browsers) but behind the scenes it can be read by any application that is compatible with these markup languages. So when any application, such as a next-generation search engine, sees a Web page or data record that contains RDF or OWL metadata, it can then use that metadata to understand what that page or data record means, is about, what it is related to, and how to interpret it. With Semantic Web metadata in place, searches on the Web will be as, or even more, precise as those in any database. But that is just the beginning of what the Semantic Web enables. Beyond merely improving search, the Semantic Web actually transforms the Web into a database—a worldwide database in which data records can be moved around, shared, and linked together in new ways.

 On the basis of the technologies of The Semantic Web and the Web 3.0 era, we will then be able to enter the fourth decade of the Web (“Web 4.0”—2020—2030) in which the shift will turn back to the front-end of the Web. The Semantic Web doesn’t just add metadata about the meaning of information to the Web, it also enables metadata to be added about relationships, conceptual linkages, logical connections, and even logical rules. On the basis of this additional metadata, Web users and other applications will be able to harness the power of intelligent agents that will search the Web for things that interest them, make suggestions and recommendations, and even potentially transact on their behalf. This will open the door to a new kind of user-interface to the Web that is smarter and more conversational in nature, in which users will enter into dialogues with agents and interact with them search the Web and make decisions. A conversational interface to the Web will be more appropriate in the increasingly mobile world, when users will mostly interact with the Web from small portable mobile or embedded devices.

 Users on mobile devices that have little to no screen real-estate will need a more productive way to interact with the Web than through a miniature browser; nobody likes sorting through pages of Google results on a cell phone. Instead, they will want to simply ask a question (perhaps through a voice interface, rather than typing with their thumbs) and have a virtual intelligent assistant dispatch agents to find the best answers and then report back to them with results or to ask further questions or for a decision.

 Smart, interactive conversational interfaces and intelligent agent-based virtual assistants are possible today, but only in narrow domains. In the Web 4.0 era they may in fact be our primary way of interacting with the whole Web and may be built into the user interface of most search engines, personal email providers, and leading Websites.

The Virtualization of Knowledge and Intelligence

In the long-term, the Semantic Web provides a way to move much of the “intelligence” that currently resides in the minds of individuals, groups and organizations, and/or that is hard-coded into various software and Web applications, out onto the Web itself. It provides a way to virtualize knowledge and intelligence in an explicitly machine-readable, universally accessible form. In other words, it provides a way to start making the Web “smarter.”

 Knowledge and expertise that previously only existed in people’s heads, or had to be painstakingly coded into each particular vertical software application, will be represented in a form of universally readable metadata on the Web—just like HTML documents today. In other words, using the Semantic Web you can publish knowledge and even the underlying conceptual frameworks, rules and heuristics that embody domain expertise, on the Web in an abstract, machine-readable form.

 There are many benefits that stem from this. For one thing, it will make it much easier to write smart software applications because much of the necessary “smarts” will not reside in the applications at all, but will rather live out there on the Web.

 For example, to write an application that can intelligently assist with travel logistics, a developer will simply be able to point it at existing sets of knowledge and rules that exist for the travel domain on the Web already. The application will be able to draw on those pools of existing domain-knowledge without having to be specifically programmed to do so, because it understands the underlying standards of the Semantic Web. Similarly, the same application could just as easily help someone trade on the stock market, by simply pointing to domain knowledge on Semantic Web about finance and investment.

 As more pools of domain knowledge are added to the Web around various verticals, all applications will potentially benefit. This sets up a kind of network effect in which a global knowledge commons begins to form and self-amplify over time. For example, first the travel domain is added to the Semantic Web. Then someone else adds domain knowledge about geography and links them together. Another group then adds domain knowledge about hotels, and another one adds domain knowledge about weather—and these all connect to each other in various ways.

 With all of this interconnected knowledge on the Web in machine-readable form, application developers can then more easily and quickly write applications that understand concepts and rules related to booking travel reservations, and that can cross-reference reservation information with knowledge about geographic places, relevant weather, and hotels in those locations. And in the other direction, someone booking a hotel can then find information about relevant weather and book travel to get to that hotel. This is just one example. There are an infinite range of other possibilities for these technologies across all domains.

 The key point of all this is that The Semantic Web enables applications to become thinner, yet at the same time smarter, by drawing on the collective intelligence embodied by the Web itself. It will become possible to write applications that understand one or more specialized vertical domains faster, and ultimately applications will become more general—they will be able to dynamically load in specialized domain knowledge for whatever domain is needed, without having to be specifically programmed or limited to just those domains.

 Application developers will be able to draw on the knowledge added to the Web by others, instead of having to reinvent the wheel by programming all that knowledge directly into their applications every time. And in turn, the knowledge that their applications create can, if they want to allow it, be published back onto the Web for other applications to draw on as well.

Semantic Web as The Next Leap in Human Collective Intelligence

Looking at the evolution of the Semantic Web in historical context, we can view it as the next big step in a longer process of the evolution of human collective intelligence.

 Before the invention of written language, knowledge could only be communicated verbally and was handed down through oral traditions. During this period, one had to be in immediate physical proximity of someone who had certain knowledge in order to receive it from them. This meant that the maximum effective range of human collective intelligence was quite short in space and time.

 With the invention of writing, and eventually printing, humanity was able to process knowledge over longer distances in space and time, and with less reliance on particular individuals. People could now engage in dialogues and dialectics with larger groups of people in more places, across larger distances in space, and with more precision over larger ranges of time.

 The printing press took this to a new level by starting the process of mass-distribution of knowledge, but it still relied on an expensive physical manufacturing process and a paper medium that was perishable and costly to store and move around.

 With advent of electronic communications of various forms, humanity achieved many milestones—the transmission of knowledge could take place at the speed of light, and using digital storage media we were freed from the limitations of the paper medium.

 The Internet and the Web transformed the process of distributing knowledge even further—enabling a global knowledge commons to emerge. The Internet and Web enable anyone and everyone to become providers of knowledge, not just consumers—a fundamental shift in the way that knowledge transmission and media function. They are not just about the mass-distribution and mass-consumption of knowledge; they enable the mass-creation of knowledge. In some respects these technologies are analogues of the printing press in that they have democratized the process of creating, sharing and accessing knowledge by fundamentally changing the economics of the entire process—making it affordable and accessible to all.

 But even on the Web, for all its many benefits, knowledge is still not free from the limitations of the human brain. Only humans can really understand the knowledge that is represented in Web sites and databases, for example. While all other processes related to the distribution, storage and access to knowledge can now be done digitally, using software and the Web, the processes of creating, consuming and actually understanding knowledge are still limited only to living humans. That’s where the Semantic Web comes in.

Liberating Knowledge and Intelligence from Human Brains

The Semantic Web virtualizes human knowledge and expertise outside of human brains, and even outside of any particular software application—knowledge becomes essentially just more data on the Web. When we speak of knowledge here we don’t just mean information—the first-order raw data that is currently on the Web—we mean the actual meaning and interpretation of the information that is not on the Web but rather exists only in human brains.

 The Semantic Web provides a way to make the meaning and interpretation of information explicit in a form that is unambiguous and publishable, and shareable, on the Web. This will make all this knowledge understandable by software. It’s almost like the invention of a new language—a sort of meta-language for formally expressing what exactly you mean when you say something. The impact of this could be enormous.

 For the first time in human history, we won’t have to rely only on humans to create, understand and consume knowledge—our machines will be able to help us do this. They will help us work, collaborate, create, explore, monitor, discover, search, innovate, connect, and synthesize. This will open the door to an almost unimaginable amplification of the human mind, and human collective intelligence on this planet. At first the impact of this will largely be focused around assisting humans with simple clerical and research tasks, but the process will inevitably continue to evolve to a point where software will begin to originate new knowledge for us, advise us, and eventually to even start making certain types of decisions on our behalf.

 Although the Semantic Web has barely moved from the lab to the mainstream Internet, it is in fact much farther along than most people realize. Today there are already semantic applications under development that can organize all your information automatically, make recommendations based on your dynamically changing interests, identify new connections between ideas or documents in different places, make logical inferences or discover contradictions, and even make discoveries by doing proofs and explorations based on available data.

 Within a few years these capabilities will begin to filter out to the mainstream users of the Internet, and with a decade or two at most, they will become commonplace. There are only a few billion humans today, and each of us can only cope with a small amount of information and relationships before we become overloaded. But in an era of machine understanding of human knowledge we may potentially be able to leverage thousands to millions of software agents to help us. This will vastly increase our ability to cope with masses of information and relationships productively. In an increasingly complex, distributed, and rapidly changing world, we simply will not be able to cope in the future without help. The Semantic Web provides one path to solving these problems, enabling us to remain productive in the future.

Amplifying Human Collective Intelligence

The Semantic Web does not replace humans or take them out of the equation. It simply reduces the load on humans, freeing them from some of the pain of information overload, and providing a new path for software to begin to augment and even amplify human collective intelligence.

 Today there are several barriers to human collective intelligence that arise from basic limitations of the human brain. Human individuals, and groups of humans, simply cannot process or share knowledge effectively beyond a certain level of information or relationship complexity and change. For this reason, collaboration and collective intelligence are often easier to achieve and yield better results in small groups than large groups.

 As group size increases, productive collective intelligence becomes dramatically harder to achieve. Thus, ironically even though larger groups offer the potential for exponential increases in collective intelligence, in practice the opposite is usually the result: the larger teams get, the dumber they get. An entire industry of management consultants and facilitators exists because of these inefficiencies.

 The Semantic Web may be able to help with this age-old problem. By enabling software to understand information and relationships, we may be able to begin to automatically and intelligently facilitate interpersonal and group collaboration and knowledge management, and this may finally enable larger groups to become exponentially smarter instead of dumber.

Twine.com—A New Service for Collective Intelligence

My own company, Radar Networks, has recently introduced a new service based on the Semantic Web, called Twine (www.twine.com) that focuses on amplifying human collective intelligence. Twine helps individuals and groups manage and share knowledge more productively, using the Semantic Web.

 As people use Twine it learns from them and automatically organizes and connects their information with other related information, saving them valuable time and enabling them to discover connected knowledge. Twine provides individuals and groups with a smart virtual environment for their knowledge.

 Twine works with all kinds of knowledge—email, RSS, Web pages, documents, photos, videos, audio, contact records, or anything else. Regardless of where information actually resides, Twine enables users to view it as if it were in one place, and to see how it is connected and organized. Twine also automatically helps to make sense of information and to make it more easily searchable.

 Twine is a Web-based online service that is completely built using the Semantic Web. Although it is only in early beta-testing at the time of this writing, it is already demonstrating that intelligent machine-augmentation of individual and group knowledge management is possible and improves productivity and collaboration.

 As Twine unfolds and spreads to more individuals, groups and teams, and organizations and communities, it has the potential to become a new backbone for collective intelligence and knowledge sharing worldwide. At least that is the vision of the project. Time will tell whether we succeed it.

From Global Knowledge Commons to Global Brain

If the Semantic Web develops as predicted, it is possible that within 20 years much, if not all, human knowledge will be represented on the Web in machine-understandable form. We have seen the beginnings of this trend with services such as the Wikipedia. More recently, another initiative called the DBpedia is creating a Semantic Web version of the Wikipedia. But this is just the start of this trend.

 As more and more applications and services start producing Semantic Web metadata and exposing it back to other applications and services on the Web, we will begin to create a new global knowledge commons. At first these different services will function like islands of knowledge, but then they will begin to interconnect.

 A piece of knowledge in one place will link to and from pieces of knowledge in other places. Eventually this will become a giant associative network, not so unlike the brain, but on a global scale. And as people and applications surf through its connections and consume its knowledge, adding new knowledge and connections back to it as they do, it will change and self-organize dynamically. Just as the first generations of the Web have enabled a global medium for “hypertext,” the Semantic Web will enable a global medium for “hyperdata.”

 As one projects the future evolution of the Web and the emerging Semantic Web, one cannot help but notice certain similarities to the human mind. Some have even ventured to call this the beginning of an emerging “Global Brain.” It is too early to tell how similar it will truly be to the actual human brain. However we can already predict with confidence that it will a system that collectively will be capable of at least rudimentary learning, memory, perception, planning and reasoning.

 The human brain is a massively parallel collective intelligence engine in which billions of neurons interact across trillions of connections to process and generate knowledge.

 Similarly, the collective intelligence of the Web will involve the combined interactions and intelligence of billions of humans and machines across trillions of relationships. These processes will not be guided centrally, and the system will most likely not be centralized around a single construct of a “self” nor will it have anything like a human body.

 While it will be possible to say the system as a whole is intelligent, it will be difficult to locate any particular source of that intelligence; the intelligence will come from everywhere: from the humans, the software and even the data and links that comprise the Web.

 Because the Web is quite different from the human brain, it is likely that its intelligence will be different from what we think of as human intelligence today. But it will nonetheless be intelligent—in a massively distributed, emergent, and chaotic way that we humans may not be able to even comprehend. The “thoughts” the Web will think may be just too vast and complex for us to even recognize, let alone imagine or understand. Yet perhaps in decade-long time-scales at least, we will begin to be able to see the outlines of its thinking.

My Visit to DERI -- World's Premier Semantic Web Research Institute

Earlier this month I had the opportunity to visit, and speak at, the Digital Enterprise Research Institute (DERI), located in Galway, Ireland. My hosts were Stefan Decker, the director of the lab, and John Breslin who is heading the SIOC project.

DERI has become the world's premier research institute for the Semantic Web. Everyone working in the field should know about them, and if you can, you should visit the lab to see what's happening there.

Part of the National University of Ireland, Galway. With over 100 researchers focused solely on the Semantic Web, and very significant financial backing, DERI has, to my knowledge, the highest concentration of Semantic Web expertise on the planet today. Needless to say, I was very impressed with what I saw there. Here is a brief synopsis of some of the projects that I was introduced to:

• Semantic Web Search Engine (SWSE) and YARS, a massively scalable triplestore.  These projects are concerned with crawling and indexing the information on the Semantic Web so that end-users can find it. They have done good work on consolidating data and also on building a highly scalable triplestore architecture.
• Sindice -- An API and search infrastructure for the Semantic Web. This project is focused on providing a rapid indexing API that apps can use to get their semantic content indexed, and that can also be used by apps to do semantic searches and retrieve semantic content from the rest of the Semantic Web. Sindice provides Web-scale semantic search capabilities to any semantic application or service.
• SIOC -- Semantically Interlinked Online Communities. This is an ontology for linking and sharing data across online communities in an open manner, that is getting a lot of traction. SIOC is on its way to becoming a standard and may play a big role in enabling portability and interoperability of social Web data.
• JeromeDL is developing technology for semantically enabled digital libraries. I was impressed with the powerful faceted navigation and search capabilities they demonstrated.
  
• notitio.us. is a project for personal knowledge management of bookmarks and unstructured data.
• SCOT, OpenTagging and Int.ere.st.  These projects are focused on making tags more interoperable, and for generating social networks and communities from tags. They provide a richer tag ontology and framework for representing, connecting and sharing tags across applications.
• Semantic Web Services.  One of the big opportunities for the Semantic Web that is often overlooked by the media is Web services. Semantics can be used to describe Web services so they can find one another and connect, and even to compose and orchestrate transactions and other solutions across networks of Web services, using rules and reasoning capabilities. Think of this as dynamic semantic middleware, with reasoning built-in.
• eLite. I was introduced to the eLite project, a large e-learning initiative that is applying the Semantic Web.
• Nepomuk.  Nepomuk is a large effort supported by many big industry players. They are making a social semantic desktop and a set of developer tools and libraries for semantic applications that are being shipped in the Linux KDE distribution. This is a big step for the Semantic Web!
• Semantic Reality. Last but not least, and perhaps one of the most eye-opening demos I saw at DERI, is the Semantic Reality project. They are using semantics to integrate sensors with the real world. They are creating an infrastructure that can scale to handle trillions of sensors eventually. Among other things I saw, you can ask things like "where are my keys?" and the system will search a network of sensors and show you a live image of your keys on the desk where you left them, and even give you a map showing the exact location. The service can also email you or phone you when things happen in the real world that you care about -- for example, if someone opens the door to your office, or a file cabinet, or your car, etc. Very groundbreaking research that could seed an entire new industry.

In summary, my visit to DERI was really eye-opening and impressive. I recommend that major organizations that want to really see the potential of the Semantic Web, and get involved on a research and development level, should consider a relationship with DERI -- they are clearly the leader in the space.

Twine Perspective on Yahoo Semantic Web Search Announcement

The Beginning of the Mainstream Semantic Web?

It is being reported that Yahoo will be indexing a wide array of structured metadata, including Semantic Web metadata. This will make Yahoo's search index potentially better than Google's, although it will also open their index up to sophisticated attempts to "game the system" as well that will need to be solved. But in any event, this will undoubtedly prod Google to begin indexing and making sense of structured metadata as well (actually, Google is already indexing FOAF, a Semantic Web metadata format).

I believe Yahoo's announcement marks the beginning of the mainstream Semantic Web. It should quickly catalyze an arms race by search engines, advertisers, and content providers to make the best use of semantic metadata on the Web. This will benefit the entire semantic sector and all players in it.

As they say, "a rising tide lifts all boats."

Where Twine Fits Into This Ecosystem

From the perspective of a company working on a large Semantic Web driven portal venture (Twine), and full platform for semantic applications (and search), this is good news. We'll be happy to open up Twine's content to Yahoo's index (when we go into General Availability in the summer timeframe, or maybe even sooner...). In addition, as more content providers add metadata to their content, it will make Twine's job of helping users collect, organize, share and discover interesting content, that much easier.

Where does Twine fit into the emerging Semantic Web ecosystem? Twine provides presence and content on the Semantic Web. It enables individuals and groups to homestead on the Semantic Web and get immediate value, without having to learn RDF.

Currently we are not going after the "be the search engine of the Semantic Web" opportunity -- we are focused on the "help users manage their information and connect with others who share their interests" and the "build thriving communities of interest" opportunities.

Our feeling is that incumbent search engines are probably best positioned to win the search engine of the entire Semantic Web war, when they decide to (as Yahoo just did, and Google most likely will soon decide to do as well...).

Twine is generating high-quality Semantic Web metadata about people, groups, topics of interest, and resources on the Web (Web pages, images, videos, books, products, documents, etc.). The metadata we are creating results from a combination of automated processing and user-contributions from our community.

The metadata Twine generates is then provided back to the users and community as open RDF that can be accessed and reused elsewhere. So we are effectively making a semantic graph of RDF about content around the Web, and related people, groups and their interests. Ultimately we become a semantic annotation layer above the Web. I can imagine that this is a dataset that Yahoo and Google and many others are going to want to be able to search.

The content in Twine is rapidly growing into a large semantic graph of information around people, groups and interests on the Web. We and our users are producing a large volume of high-quality original content and semantic metadata about existing Web content, that will undoubtedly make the Yahoo index much richer (and will drive traffic back to Twine and the sites we link back to from our graph).

The Semantic Web Eliminates Traditional Silos By Opening Up and Linking the Data

Twine is a hosted online service, but is not actually a "silo" in the traditional sense because all of our data is represented in open-standards-based RDF, and we are already providing access to that data on an experimental basis, and will provide even more via upcoming API's in the future.

This means that the data Twine is creating and gathering, is open, linked data, that can be reused in other applications and services. Ultimately this makes Twine a part of a growing distributed ecosystem. Semantic Web metadata in RDF and OWL is even better than microformats because it carries its own meaning about how to use it. Software that speaks RDF and OWL can instantly reuse it without any additional programming. To learn more about Twine's open RDF availability, see the Twine Tour: Semantic Web section.

I believe that the open-standards of the Semantic Web eliminate silos. Effectively all services that participate in using these standards and make their data open are becoming part of one big distributed worldwide database, rather than old fashioned silos. That's the benefit of open linked data services powered by RDF, OWL, SPARQL, and GRDDL.

How Will End-Users Participate in the Semantic Web?

If Yahoo and possibly Google make search better by indexing all sorts of metadata, there is then an even larger opportunity to help non-technical end-users create and use that metadata. This is where services like Twine fits in. End-users need ways to author, organize, share, reuse, and discover Semantic Web content.

We don't believe ordinary Webmasters or end-users are going to write microformats or RDF by hand. Even hard-core Semantic Web researchers don't do that. Ultimately end-users need user-friendly services that do this for them automatically, or at least make it easier to do. Twine helps these users to participate in the Semantic Web, without requiring them to have a degree in computer science. Twine provides an (increasingly) user-friendly hosted place where users can collect, organize, share and discover other interesting content around their interests, using the Semantic Web transparently "under the hood."

Concluding Thoughts

In short, Twine is where ordinary non-technical individuals and groups can join the Semantic Web, get a presence there, and start using it in useful ways, today. If Yahoo and Google become the search engines of the Semantic Web, that will make Twine even more necessary as the place where end-users can participate in this emerging ecosystem. We believe our community, and the rich the semantic graph we are growing will become increasingly valuable as the major search engines begin to index the Semantic Web.

But this is just the beginning of our story. Twine is designed to become a platform that others can build on and integrate with as well. There is more to our strategy than we have currently opened up about. In time we will be telling the rest of our story. We have some fun surprises in store in the future...

There are now well over 30,000 users in the queue to get into the Twine beta. We're going to start letting people in from the waiting list in waves and it should take about a month or two to let everyone in.

But what good is a waiting list if there's no way to cut to the front, right? Fortunately, there is a way to skip ahead to the front of the line...

Write a blog post about Twine on your blog and why you want early access, and send me the link to nova (at) radarnetworks (dot) com. along with your first name, last name, and email address. If I like your post, I'll get you an early access VIP pass to front of the line.

See you in Twine!

Insightful Article About Twine

Carla Thompson, an analyst for Guidewire Group, has written what I think is a very insightful article about her experience participating in the early-access wave of the Twine beta.

We are now starting to let the press in and next week we will begin to let waves of people in from our over 30,000 user wait list. We will be letting people into the beta in waves every week going forward.

As Carla notes, Twine is a work in progress and we are mainly focused on learning from our users now. We have lots more to do, but we're very excited about the direction Twine is headed in, and it's really great to see Twine getting so much active use.

My Commentary: Radar Networks Raises $13M for Twine

I am pleased to announce that my company Radar Networks, has raised a $13M Series B investment round to grow our product, Twine. The investment comes from Velocity Interactive Group, DFJ, and Vulcan. Ross Levinsohn -- the man who acquired and ran MySpace for Fox Interactive -- will be joining our board. I'm very excited to be working with Ross and to have his help guiding Twine as it grows.

We are planning to use these funds to begin rolling Twine out to broader consumer markets as part of our multi-year plan to build Twine into the leading service for organizing, sharing and discovering information around interests. One of the key themes of Web 3.0 is to be help people make sense of the overwhelming amount of information and change in the online world, and at Twine, we think interests are going to play a key organizing role in that process.

Your interests comprise the portion of your information and relationships that are actually important enough that you want to keep track of them and share them with others. The question that Twine addresses is how to help individuals and groups more efficiently locate, manage and communicate around their interests in the onslaught of online information they have to cope with. The solution to information overload is not to organize all the information in the world (an impossible task), it is to help individuals and groups organize THEIR information (a much more feasible goal).

In March we are going to expand the Twine beta to begin letting more people in. Currently we have around 30,000 people on the wait-list and more coming in steadily. In March we will start letting all of these people in, gradually in waves of a few thousand at a time, and letting them invite their friends in. So to get into Twine you need to sign up on the list on the Twine site, or have a friend who is already in the service invite you in. I look forward to seeing you in Twine!

The last few months of closed beta have been very helpful in getting a lot of useful feedback and testing that has helped us improve the product in many ways. This next wave will be an exciting phase for Twine as we begin to really grow the service with more users. I am sure there will be a lot of great feedback and improvements that result from this.

However, even though we will be letting more people in soon, we are still very much in beta and will be for quite some time to come -- There will still be things that aren't finished, aren't perfect, or aren't there yet -- so your patience will be appreciated as we continue to work on Twine over the coming year. We are letting people in to help us guide the service in the right direction, and to learn from our users. Today Twine is about 10% of what we have planned for it. First we have to get the basics right -- then, in the coming year, we will really start to surface more of the power of the underlying semantic platform. We're psyched to get all this built -- what we have planned is truly exciting!
