I just read this really cool idea about how to design a programming language for the global brain -- think of it as grid computing, but where some of the agents in the grid are humans and others are computers, working together to solve problems. I've had similar ideas to this over the years, for example the use of collaborative networks to mark up and tag content on the Semantic Web, as well as various forms of expertise referral networks. What I like about this new proposal is that it suggests an actual language for writing global mind programs. That's a new angle. Brilliant.
