Accelerando by Charles Stross is a wonderful post-cyberpunk novel about the 21st century and how it might evolve. The book has more extrapolations from the modern web economy than a dog has fleas.
Basically, though, Stross' model of civilization as a collection of economic business models and the idea of extending BPM into the political arena is intriguing. I particularly liked the comment about purchasing an off the shelf legal system then conforming to it
So I heartily recommend it for anyone interested in wild eyed extrapolation of web 2.0 concepts.
