Ed Felten blogged the conference. Here’s his summary of what Yochai Benkler said:

He has two themes: decentralization of creation, and emergence of a political movement around that creation. Possibility of altering the politics in three ways. First, the changing relationship between creators and users and growth in the number of creators changes how people relate to the rules. Second, we see existence proofs of the possible success of decentralized production: Linux, Skype, Flickr, Wikipedia. Third, a shift away from centralized, mass, broadcast media. He talks about political movements like free culture, Internet freedom, etc. He says these movements are coalescing and allying with each other and with other powers such as companies or nations. He is skeptical of the direct value of public reason/persuasion. He thinks instead that changing social practices will have a bigger impact in the long run.
