"Clay Shirky's work focuses on the rising usefulness of decentralized technologies such as peer-to-peer, wireless networks, social software and open-source development. New technologies are enabling new kinds of cooperative structures to flourish as a way of getting things done in business, science, the arts and elsewhere, as an alternative to centralized and institutional structures, which he sees as self-limiting."
Brilliant book on how to leverage our new found connectivity to solve problems on a mass scale. Also, does a great job of helping you think about use of modern technology in an innovative way. Clay Shirky rules.
