Sneak Peak - Siri -- Interview with Tom Gruber

Sneak Preview of Siri – The Virtual Assistant that will Make Everyone Love the iPhone, Part 2: The Technical Stuff

 

In Part-One of this article on TechCrunch, I covered the emerging paradigm of Virtual Assistants and explored a first look at a new product in this category called Siri. In this article, Part-Two, I interview Tom Gruber, CTO of Siri, about the history, key ideas, and technical foundations of the product:

Nova Spivack: Can you give me a more precise definition of a Virtual Assistant?

Tom Gruber: A virtual personal assistant is a software system that

• Helps the user find or do something (focus on tasks, rather than information)
• Understands the user's intent (interpreting language) and context (location, schedule, history)
• Works on the user's behalf, orchestrating multiple services and information sources to help complete the task

In other words, an assistant helps me do things by understanding me and working for me.    This may seem quite general, but it is a fundamental shift from the way the Internet works today.  Portals, search engines, and web sites are helpful but they don't do things for me - I have to use them as tools to do something, and I have to adapt to their ways of taking input.

Nova Spivack: Siri is hoping to kick-start the revival of the Virtual Assistant category, for the Web. This is an idea which has a rich history. What are some of the past examples that have influenced your thinking?

Tom Gruber: The idea of interacting with a computer via a conversational interface with an assistant has excited the imagination for some time.  Apple's famous Knowledge Navigator video offered a compelling vision, in which a talking head agent helped a professional deal with schedules and access information on the net.  The late Michael Dertouzos, head of MIT's Computer Science Lab, wrote convincingly about the assistant metaphor as the natural way to interact with computers in his book "The Unfinished Revolution: Human-Centered Computers and What They Can Do For Us".  These accounts of the future say that you should be able to talk to your computer in your own words, saying what you want to do, with the computer talking back to ask clarifying questions and explain results.  These are hallmarks of the Siri assistant.  Some of the elements of these visions are beyond what Siri does, such as general reasoning about science in the Knowledge Navigator.  Or self-awareness a la Singularity.  But Siri is the real thing, using real AI technology, just made very practical on a small set of domains. The breakthrough is to bring this vision to a mainstream market, taking maximum advantage of the mobile context and internet service ecosystems.  

Nova Spivack: Tell me about the CALO project, that Siri spun out from. (Disclosure: my company, Radar Networks, consulted to SRI in the early days on the CALO project, to provide assistance with Semantic Web development)

Tom Gruber: Siri has its roots in the DARPA CALO project (“Cognitive Agent that Learns and Organizes”) which was led by SRI.  The goal of CALO was to develop AI technologies (dialog and natural language understanding,s understanding, machine learning, evidential and probabilistic reasoning, ontology and knowledge representation, planning, reasoning, service delegation) all integrated into a virtual assistant that helps people do things.  It pushed the limits on machine learning and speech, and also showed the technical feasibility of a task-focused virtual assistant that uses knowledge of user context and multiple sources to help solve problems. 

Siri is integrating, commercializing, scaling, and applying these technologies to a consumer-focused virtual assistant.  Siri was under development for several years during and after the CALO project at SRI. It was designed as an independent architecture, tightly integrating the best ideas from CALO but free of the constraints of a national distributed research project. The Siri.com team has been evolving and hardening the technology since January 2008.

Nova Spivack: What are primary aspects of Siri that you would say are “novel”?

Tom Gruber: The demands of the consumer internet focus -- instant usability and robust interaction with the evolving web -- has driven us to come up with some new innovations:

• A conversational interface that combines the best of speech and semantic language understanding with an interactive dialog that helps guide people toward saying what they want to do and getting it done. The conversational interface allows for much more interactivity that one-shot search style interfaces, which aids usability and improves intent understanding.  For example, if Siri didn't quite hear what you said, or isn't sure what you meant, it can ask for clarifying information.   For example, it can prompt on ambiguity: did you mean pizza restaurants in Chicago or Chicago-style pizza places near you?  It can also make reasonable guesses based on context.  Walking around with the phone at lunchtime, if the speech interpretation comes back with something garbled about food you probably meant "places to eat near my current location".  If this assumption isn't right, it is easy to correct in a conversation.  
• Semantic auto-complete - a combination of the familiar "autocomplete" interface of search boxes with a semantic and linguistic model of what might be worth saying.  The so-called "semantic completion" makes it possible to rapidly state complex requests (Italian restaurants in the SOMA neighborhood of San Francisco that have tables available tonight) with just a few clicks.  It's sort of like the power of faceted search a la Kayak, but packaged in a clever command line style interface that works in small form factor and low bandwidth environments. 
• Service delegation - Siri is particularly deep in technology for operationalizing a user's intent into computational form, dispatching to multiple, heterogeneous services, gathering and integrating results, and presenting them back to the user as a set of solutions to their request.  In a restaurant selection task, for instance, Siri combines information from many different sources (local business directories, geospatial databases, restaurant guides, restaurant review sources, online reservation services, and the user's own favorites) to show a set of candidates that meet the intent expressed in the user's natural language request.  

Nova Spivack: Why do you think Siri will succeed when other AI-inspired projects have failed to meet expectations?

Tom Gruber: In general my answer is that Siri is more focused. We can break this down into three areas of focus:

• Task focus. Siri is very focused on a bounded set of specific human tasks, like finding something to do, going out with friends, and getting around town.  This task focus allows it to have a very rich model of its domain of competence, which makes everything more tractable from language understanding to reasoning to service invocation and results presentation
  
• Structured data focus. The kinds of tasks that Siri is particularly good at involve semistructured data, usually on tasks involving multiple criteria and drawing from multiple sources.  For example, to help find a place to eat, user preferences for cuisine, price range, location, or even specific food items come into play.  Combining results from multiple sources requires reasoning about domain entity identity and the relative capabilities of different information providers.  These are hard problems of semantic information processing and integration that are difficult but feasible today using the latest AI technologies. 
• Architecture focus.  Siri is built from deep experience in integrating multiple advanced technologies into a platform designed expressly for virtual assistants.  Siri co-founder Adam Cheyer was chief architect of the CALO project, and has applied a career of experience to design the platform of the Siri product.  Leading the CALO project taught him a lot about what works and doesn't when applying AI to build a virtual assistant.   Adam and I also have rather unique experience in combining AI with intelligent interfaces and web-scale knowledge integration.  The result is a "pure  play" dedicated architecture for virtual assistants, integrating all the components of intent understanding, service delegation, and dialog flow management.  We have avoided the need to solve general AI problems by concentrating on only what is needed for a virtual assistant, and have chosen to begin with a finite set of vertical domains serving mobile use cases.

Nova Spivack: Why did you design Siri primarily for mobile devices, rather than Web browsers in general?

Tom Gruber: Rather than trying to be like a search engine to all the world's information, Siri is going after mobile use cases where deep models of context (place, time, personal history) and limited form factors magnify the power of an intelligent interface.  The smaller the form factor, the more mobile the context, the more limited the bandwidth : the more it is important that the interface make intelligent use of the user's attention and the resources at hand.  In other words, "smaller needs to be smarter."  And the benefits of being offered just the right level of detail or being prompted with just the right questions can make the difference between task completion or failure.  When you are on the go, you just don't have time to wade through pages of links and disjoint interfaces, many of which are not suitable to mobile at all.  

Nova Spivack: What language and platform is Siri written in?

Tom Gruber: Java, Javascript, and Objective C (for the iPhone)

Nova Spivack: What about the Semantic Web? Is Siri built with Semantic Web open-standards such as RDF and OWL, Sparql?

Tom Gruber: No, we connect to partners on the web using structured APIs, some of which do use the Semantic Web standards.  A site that exposes RDF usually has an API that is easy to deal with, which makes our life easier.  For instance, we use geonames.org as one of our geospatial information sources. It is a full-on Semantic Web endpoint, and that makes it easy to deal with.  The more the API declares its data model, the more automated we can make our coupling to it.

Nova Spivack: Siri seems smart, at least about the kinds of tasks it was designed for. How is the knowledge represented in Siri – is it an ontology or something else?

Tom Gruber: Siri's knowledge is represented in a unified modeling system that combines ontologies, inference networks, pattern matching agents, dictionaries, and dialog models.  As much as possible we represent things declaratively (i.e., as data in models, not lines of code).  This is a tried and true best practice for complex AI systems.  This makes the whole system more robust and scalable, and the development process more agile.  It also helps with reasoning and learning, since Siri can look at what it knows and think about similarities and generalizations at a semantic level.

Nova Spivack: Will Siri be part of the Semantic Web, or at least the open linked data Web (by making open API’s, sharing of linked data, RDF, available, etc.)?

Tom Gruber: Siri isn't a source of data, so it doesn't expose data using Semantic Web standards.  In the Semantic Web ecosystem, it is doing something like the vision of a semantic desktop - an intelligent interface that knows about user needs and sources of information to meet those needs, and intermediates.  The original Semantic Web article in Scientific American included use cases that an assistant would do (check calendars, look for things based on multiple structured criteria, route planning, etc.).  The Semantic Web vision focused on exposing the structured data, but it assumes APIs that can do transactions on the data.  For example, if a virtual assistant wants to schedule a dinner it needs more than the information about the free/busy schedules of participants, it needs API access to their calendars with appropriate credentials, ways of communicating with the participants via APIs to their email/sms/phone, and so forth.  Siri is building on the ecosystem of APIs, which are better if they declare the meaning of the data in and out via ontologies.  That is the original purpose of ontologies-as-specification that I promoted in the 1990s - to help specify how to interact with these agents via knowledge-level APIs.

Siri does, however, benefit greatly from standards for talking about space and time, identity (of people, places, and things), and authentication.  As I called for in my Semantic Web talk in 2007, there is no reason we should be string matching on city names, business names, user names, etc.  

All players near the user in the ecommerce value chain get better when the information that the users need can be unambiguously identified, compared, and combined.  Legitimate service providers on the supply end of the value chain also benefit, because structured data is harder to scam than text.  So if some service provider offers a multi-criteria decision making service, say, to help make a product purchase in some domain, it is much easier to do fraud detection when the product instances, features, prices, and transaction availability information are all structured data.

Nova Spivack: Siri appears to be able to handle requests in natural language. How good is the natural language processing (NLP) behind it? How have you made it better than other NLP?

Tom Gruber: Siri's top line measure of success is task completion (not relevance).  A subtask is intent recognition, and subtask of that is NLP.  Speech is another element, which couples to NLP and adds its own issues.  In this context, Siri's NLP is "pretty darn good" -- if the user is talking about something in Siri's domains of competence, its intent understanding is right the vast majority of the time, even in the face of noise from speech, single finger typing, and bad habits from too much keywordese.  All NLP is tuned for some class of natural language, and Siri's is tuned for things that people might want to say when talking to a virtual assistant on their phone.  We evaluate against a corpus, but I don't know how it would compare to standard message and news corpuses using by the NLP research community.

Nova Spivack: Did you develop your own speech interface, or are you using third-party system for that? How good is it? Is it battle-tested?

Tom Gruber: We use third party speech systems, and are architected so we can swap them out and experiment.  The one we are currently using has millions of users and continuously updates its models based on usage.

Nova Spivack: Will Siri be able to talk back to users at any point?

Tom Gruber: It could use speech synthesis for output, for the appropriate contexts.  I have a long standing interest in this, as my early graduate work was in communication prosthesis.  In the current mobile internet world, however, iPhone-sized screens and 3G networks make it possible to do so more much than read menu items over the phone.  For the blind, embedded appliances, and other applications it would make sense to give Siri voice output.

Nova Spivack: Can you give me more examples of how the NLP in Siri works?

Tom Gruber: Sure, here’s an example, published in the Technology Review, that illustrates what’s going on in a typical dialogue with Siri. (Click link to view the table)

Nova Spivack: How personalized does Siri get – will it recommend different things to me depending on where I am when I ask, and/or what I’ve done in the past? Does it learn?

Tom Gruber: Siri does learn in simple ways today, and it will get more sophisticated with time.  As you said, Siri is already personalized based on immediate context, conversational history, and personal information such as where you live.  Siri doesn't forget things from request to request, as do stateless systems like search engines. It always considers the user model along with the domain and task models when coming up with results.  The evolution in learning comes as users have a history with Siri, which gives it a chance to make some generalizations about preferences.  There is a natural progression with virtual assistants from doing exactly what they are asked, to making recommendations based on assumptions about intent and preference. That is the curve we will explore with experience.

Nova Spivack: How does Siri know what is in various external services – are you mining and doing extraction on their data, or is it all just real-time API calls?

Tom Gruber: For its current domains Siri uses dozens of APIs, and connects to them in both realtime access and batch data synchronization modes.  Siri knows about the data because we (humans) explicitly model what is in those sources.  With declarative representations of data and API capabilities, Siri can reason about the various capabilities of its sources at run time to figure out which combination would best serve the current user request.  For sources that do not have nice APIs or expose data using standards like the Semantic Web, we can draw on a value chain of players that do extract structure by data mining and exposing APIs via scraping.

Nova Spivack: Thank you for the information, Siri might actually make me like the iPhone enough to start using one again.

Tom Gruber:   Thank you, Nova, it's a pleasure to discuss this with someone who really gets the technology and larger issues.  I hope Siri does get you to use that iPhone again.  But remember, Siri is just starting out and will sometimes say silly things.  It's easy to project intelligence onto an assistant, but Siri isn't going to pass the Turing Test.  It's just a simpler, smarter way to do what you already want to do.  It will be interesting to see how this space evolves, how people will come to understand what to expect from the little personal assistant in their pocket.

Video: My Talk on The Future of Libraries -- "Library 3.0"

If you are interested in semantics, taxonomies, education, information overload and how libraries are evolving, you may enjoy this video of my talk on the Semantic Web and the Future of Libraries at the OCLC Symposium at the American Library Association Midwinter 2009 Conference. This event focused around a dialogue between David Weinberger and myself, moderated by Roy Tennant. We were forutnate to have an audience of about 500 very vocal library directors in the audience and it was an intensive day of thinking together. Thanks to the folks at OCLC for a terrific and really engaging event!

Twine's Explosive Growth

Twine has been growing at 50% per month since launch in October. We've been keeping that quiet while we wait to see if it holds. VentureBeat just noticed and did an article about it. It turns out our January numbers are higher than Compete.com estimates and February is looking strong too. We have a slew of cool viral features coming out in the next few months too as we start to integrate with other social networks. Should be an interesting season.

Fast Company Interview -- "Connective Intelligence"

In this interview with Fast Company, I discuss my concept of "connective intelligence." Intelligence is really in the connections between things, not the things themselves. Twine facilitates smarter connections between content, and between people. This facilitates the emergence of higher levels of collective intelligence.

Interest Networks are at a Tipping Point

UPDATE: There's already a lot of good discussion going on around this post in my public twine.

I’ve been writing about a new trend that I call “interest networking” for a while now. But I wanted to take the opportunity before the public launch of Twine on Tuesday (tomorrow) to reflect on the state of this new category of applications, which I think is quickly reaching its tipping point. The concept is starting to catch on as people reach for more depth around their online interactions.

In fact – that’s the ultimate value proposition of interest networks – they move us beyond the super poke and towards something more meaningful. In the long-term view, interest networks are about building a global knowledge commons. But in the short term, the difference between social networks and interest networks is a lot like the difference between fast food and a home-cooked meal – interest networks are all about substance.

At a time when social media fatigue is setting in, the news cycle is growing shorter and shorter, and the world is delivered to us in soundbytes and catchphrases, we crave substance. We go to great lengths in pursuit of substance. Interest networks solve this problem – they deliver substance.

So, what is an interest network?

In short, if a social network is about who you are interested in, an interest network is about what you are interested in. It’s the logical next step.

Twine for example, is an interest network that helps you share information with friends, family, colleagues and groups, based on mutual interests. Individual “twines” are created for content around specific subjects. This content might include bookmarks, videos, photos, articles, e-mails, notes or even documents. Twines may be public or private and can serve individuals, small groups or even very large groups of members.

I have also written quite a bit about the Semantic Web and the Semantic Graph, and Tim Berners-Lee has recently started talking about what he calls the GGG (Giant Global Graph). Tim and I are in agreement that social networks merely articulate the relationships between people. Social networks do not surface the equally, if not more important, relationships between people and places, places and organizations, places and other places, organization and other organizations, organization and events, documents and documents, and so on.

This is where interest networks come in. It’s still early days to be clear, but interest networks are operating on the premise of tapping into a multi--dimensional graph that manifests the complexity and substance of our world, and delivers the best of that world to you, every day.

We’re seeing more and more companies think about how to capitalize on this trend. There are suddenly (it seems, but this category has been building for many months) lots of different services that can be viewed as interest networks in one way or another, and here are some examples:

• Twine (my site)
• Friendfeed
• Strands
• Intuu
• SocialMedian
• Zimesh
• Popego
• YourVersion

What all of these interest networks have in common is some sort of a bottom-up, user-driven crawl of the Web, which is the way that I’ve described Twine when we get the question about how we propose to index the entire Web (the answer: we don’t. We let our users tell us what they’re most interested in, and we follow their lead).

Most interest networks exhibit the following characteristics as well:

• They have some sort of bookmarking/submission/markup function to store and map data (often using existing metaphors, even if what’s under the hood is new)
• They also have some sort of social sharing function to provide the network benefit (this isn’t exclusive to interest networks, obviously, but it is characteristic)
• And in most cases, interest networks look to add some sort of “smarts” or “recommendations” capability to the mix (that is, you get more out than you put in)

This last bullet point is where I see next-generation interest networks really providing the most benefit over social bookmarking tools, wikis, collaboration suites and pure social networks of one kind or another.

To that end, we think that Twine is the first of a new breed of intelligent applications that really get to know you better and better over time – and that the more you use Twine, the more useful it will become. Adding your content to Twine is an investment in the future of your data, and in the future of your interests.

At first Twine begins to enrich your data with semantic tags and links to related content via our recommendations engine that learns over time. Twine also crawls any links it sees in your content and gathers related content for you automatically – adding it to your personal or group search engine for you, and further fleshing out the semantic graph of your interests which in turn results in even more relevant recommendations.

The point here is that adding content to Twine, or other next-generation interest networks, should result in increasing returns. That’s a key characteristic, in fact, of the interest networks of the future – the idea that the ratio of work (input) to utility (output) has no established ceiling.

Another key characteristic of interest networks may be in how they monetize. Instead of being advertising-driven, I think they will focus more on a marketing paradigm. They will be to marketing what search engines were to advertising. For example, Twine will be monetizing our rich model of individual and group interests, using our recommendation engine. When we roll this capability out in 2009, we will deliver extremely relevant, useful content, products and offers directly to users who have demonstrated they are really interested in such information, according to their established and ongoing preferences.

6 months ago, you could not really prove that “interest networking” was a trend, and certainly it wasn’t a clearly defined space. It was just an idea, and a goal. But like I said, I think that we’re at a tipping point, where the technology is getting to a point at which we can deliver greater substance to the user, and where the culture is starting to crave exactly this kind of service as a way of making the Web meaningful again.

I think that interest networks are a huge market opportunity for many startups thinking about what the future of the Web will be like, and I think that we’ll start to see the term used more and more widely. We may even start to see some attention from analysts -- Carla, Jeremiah, and others, are you listening?

Now, I obviously think that Twine is THE interest network of choice. After all we helped to define the category, and we’re using the Semantic Web to do it. There’s a lot of potential in our engine and our application, and the growing community of passionate users we’ve attracted.

Our 1.0 release really focuses on UE/usability, which was a huge goal for us based on user feedback from our private beta, which began in March of this year. I’ll do another post soon talking about what’s new in Twine. But our TOS (time on site) at 6 minutes/user (all time) and 12 minutes/user (over the last month) is something that the team here is most proud of – it tells us that Twine is sticky, and that “the dogs are eating the dog food.”

Now that anyone can join, it will be fun and gratifying to watch Twine grow.

Still, there is a lot more to come, and in 2009 our focus is going to shift back to extending our Semantic Web platform and turning on more of the next-generation intelligence that we’ve been building along the way. We’re going to take interest networking to a whole new level.

Stay tuned!

The Future of the Desktop

(Brief excerpt from a new post on my Public Twine -- Go there to read the whole thing and comment on it with me and others...).

I have spent the last year really thinking about the future of the Web. But lately I have been thinking more about the future of the desktop. In particular, here are some questions I am thinking about and some answers I've come up so far.

This is a raw, first-draft of what I think it will be like.

Is the desktop of the future going to just be a web-hosted version of the same old-fashioned desktop metaphors we have today?

No. We've already seen several attempts at doing that -- and they never catch on. People don't want to manage all their information on the Web in the same interface they use to manage data and apps on their local PC.

Partly this is due to the difference in user experience between using real live folders, windows and menus on a local machine and doing that in "simulated" fashion via some Flash-based or HTML-based imitation of a desktop.

Web desktops to-date have simply have been clunky and slow imitations of the real-thing at best. Others have been overly slick. But one thing they all have in common: None of them have nailed it.

Whoever does succeed in nailing this opportunity will have a real shot at becoming a very important player in the next-generation of the Web, Web 3.0.

From the points above it should be clear that I think the future of the desktop is going to be significantly different from what our desktops are like today.

It's going to be a hosted web service

Is the desktop even going to exist anymore as the Web becomes increasingly important? Yes, there is going to be some kind of interface that we consider to be our personal "home" and "workspace" -- but it will become unified across devices.

Currently we have different spaces on different devices (laptop, mobile device, PC). These will merge. In order for that to happen they will ultimately have to be provided as a service via the Web. Local clients may be created for various devices, but ultimately the most logical choice is to just use the browser as the client.

Our desktop will not come from any local device and will always be available to us on all our devices.

 

The skin of your desktop will probably appear within your local device's browser as a completely dynamically hosted web application coming from a remote server. It will load like a Web page, on-demand from a URL.

This new desktop will provide an interface both to your local device, applications and information, as well as to your online life and information.

Instead of the browser running inside, or being launched from, some kind of next-generation desktop web interface technology, it's will be the other way around: The browser will be the shell and the desktop application will run within it either as a browser add-in, or as a web-based application.

The Web 3.0 desktop is going to be completely merged with the Web -- it is going to be part of the Web. There will be no distinction between the desktop and the Web anymore.

Today we think of our Web browser running inside our desktop as an applicaiton. But actually it will be the other way around in the future: Our desktop will run inside our browser as an application.

The focus shifts from information to attention

As our digital lives shift from being focused on the old fashioned desktop (space-based metaphor) to the Web environment we will see a shift from organizing information spatially (directories, folders, desktops, etc.) to organizing information temporally (river of news, feeds, blogs, lifestreaming, microblogging).

Instead of being a big directory, the desktop of the future is going to be more like a Feed reader or social news site. The focus will be on keep up with all the stuff flowing through and what the trends are, rather than on all the stuff that is stored there already.

The focus will be on helping the user to manage their attention rather than just their information.

This is a leap to the meta-level. A second-order desktop. Instead of just being about the information (the first-order), it is going to be about what is happening with the information (the second-order).

It's going to shift us from acting as librarians to acting as daytraders.

Our digital roles are already shifting from effectively acting as "librarians" to becoming more like "daytraders." We are all focusing more on keep up with change than on organizing information today. This will continue to eat up more of our attention...

Quick Video Preview of Twine

The New Scientist just posted a quick video preview of Twine to YouTube. It only shows a tiny bit of the functionality, but it's a sneak peak.

We've been letting early beta testers into Twine and we're learning a lot from all the great feedback, and also starting to see some cool new uses of Twine. There are around 20,000 people on the wait-list already, and more joining every day. We're letting testers in slowly, focusing mainly on people who can really help us beta test the software at this early stage, as we go through iterations on the app. We're getting some very helpful user feedback to make Twine better before we open it up the world.

For now, here's a quick video preview:

Is Google Making Social Networking Middleware?

Google's recent announcement of their OpenSocial API's appears to be a new form of middleware for connecting social networks together. But it's too early to tell, since the technical details are not available yet. The notion of a middleware service for connecting social networks and sharing data between them makes a lot of sense, and if Google has really made it "open" then it could be very useful. The question remains of course, why would Google do this unless there is some way they have a unique benefit from it? My guess is that they will run advertising through this system, and will have unique advantages in their ability to target ads to people based on the social network profiles they can see via this system. We'll have to wait and see what happens, but it is interesting.

From the perspective of Radar Networks and Twine.com, this is a trend we are watching closely. It could be something to integrate with, but until we really see the technical details we'll reserve judgement.

A Video and an Audio Cast About Twine

Last night I saw that the video of my presentation of Twine at the Web 2.0 Summit is online. My session, "The Semantic Edge," featured Danny Hillis of Metaweb demoing Freebase, Barney Pell demoing Powerset, and myself Demoing Twine, followed by a brief panel discussion with Tim O'Reilly (in that order). It's a good panel and I recommend the video, however, the folks at Web 2.0 only filmed the presenters; they didn't capture what we were showing on our screens, so you have to use your imagination as we describe our demos.

An audio cast of one of my presentations about Twine to a reporter was also put online recently, for a more in-depth description.

What a Week!

What a week it has been for Radar Networks. We have worked so hard these last few days to get ready to unveil Twine, and it has been a real thrill to show our work and get such positive feedback and support from the industry, bloggers, the media and potential users.

We really didn't expect so much excitement and interest. In fact we've been totally overwhelmed by the response as thousands upon thousands of people have contacted us in the last 24 hours asking to join our beta, telling us how they would use Twine for their personal information management, their collaboration, their organizations, and their communities. Clearly there is such a strong and growing need out there for the kind of Knowledge Networking capabilities that Twine provides, and it's been great to hear the stories and make new connections with so many people who want our product. We love hearing about your interest in Twine, what you would use it for, what you want it to do, and why you need it! Keep those stories coming. We read them all and we really listen to them.

Today, in unveiling Twine, over five years of R&D, and contributions from dozens of core contributors, a dedicated group of founders and investors, and hundreds of supporters, advisors, friends and family, all came to fruition. As a company, and a team, we achieved an important milestone and we should all take some time to really appreciate what we have accomplished so far. Twine is a truly ambitious and pardigm-shifting product, that is not only technically profound but visually stunning -- There has been so much love and attention to detail in this product.

In the last 6 months, Twine has really matured into a product, a product that solves real and growing needs (for a detailed use-case see this post). And just as our product has matured, so has our organization: As we doubled in size, our corporate culture has become tremendously more interesting, innovative and fun. I could go on and on about the cool things we do as a company and the interesting people who work here. But it's the passion, dedication and talent of this team that is most inspiring. We are creating a team and a culture that truly has the potential to become a great Silicon Valley company: The kind of company that I've always wanted to build.

Although we launched today, this is really just the beginning of the real adventure. There is still much for us to build, learn about, and improve before Twine will really accomplish all the goals we have set out  for it. We have a five-year roadmap. We know this is a marathon, not a sprint and that "slow and steady wins the race." As an organization we also have much learning and growing to do. But this really doesn't feel like work -- it feels like fun -- because we all love this product and this company. We all wake up every day totally psyched to work on this.

It's been an intense, challenging, and rewarding week. Everyone on my team has impressed me and really been at the top of their game. Very few of us got any real sleep, and most of us went far beyond the call of duty. But we did it, and we did it well. As a company we have never cut corners, and we have always preferred to do things the right way, even if the right way is the hard way. But that pays off in the end. That is how great products are built. I really want to thank my co-founders, my team, my investors, advisors, friends, and family, for all their dedication and support.

Today, we showed our smiling new baby to the world, and the world smiled back.

And tonight , we partied!!!
