Dave Winer kindly posted his recording of Howard Rheingold's speech at Harvard earlier this week. I'm listening to it now. He discusses a number of different threads of research in collaboration, and draws this analogy with science: Descartes realized that the 'old ways' had run their course, and it was time for something new, a philosphical framework for scientific inquiry. Rheingold sees hints of another 'something new' in terms of how we understand how people work together, although its much to early to nail it down. Very interesting speech and discussion.
