Henry Jenkins has posted his notes to remarks at the Beyond Broadcast conference.  This is a wonderful description of Wikipedia, and the convergence of forces that creates something brand new which could not have existed before.  This is the real power in the social net, where business models are formed in ways that could not have otherwise occurred.

Wikipedia has developed strong ethical standards that enable people with wildly divergent beliefs to work together towards a common project; they focus on the shared infrastructure that they all need in order to achieve their aims rather than on the individual points of disagreement; the Wikipedia movement provides them with meaningful mechanisms that allow for the reconciliation between competing truth claims and the co-existence of differing perspectives
