There’s something very endearing about this docudrama retelling of the story of the web.
This is the ur-spring: Tim Berners Lee's original proposal for "Mesh", later "World Wide Web."
TIm Berners-Lee explains what the "graph" part of "social graph" means. I'm still not keen on the term but I really love the idea (although I also disagree about the building blocks required today).
David Smith has written a brilliant overview of how the perception of the Web is converging towards Tim Berners-Lee original vision of a read/write environment.
