I saw Clay Shirky speak at the Health2.0 conference in San Francisco a month or so ago. The guy amazes me... This video is 20 minutes worth your time!
His talk covers institutions vs. collaboration...
Institutions: requires management, exclusion (you can't hire everyone), you create a professional class
Collaboration: you bring the problem to the people, instead of bringing the people to the problem, you build groups, you coordinate group efforts
