Interview of Clay Shirky:

"Web services, by starting with a standards-driven goal, stands a much better chance in my mind of providing not only the standards and infrastructure for Web services but the spill-over: standards and infrastructure for peer-to-peer. So the obvious win for peer-to-peer from Web services is better interoperability. And I think there are a couple of important things the Web services people can learn from the peer-to-peer people as well."
