The second keynote at the AoIR 2007 conference is by MIT's Henry Jenkins, speaking on the moral economy of Web 2.0 (in a presentation coauthored with Josh Green and emerging from the work of the Convergence Culture Consortium at MIT). The central principle of Web 2.0 is to embrace the power of collective intelligence, as Kevin O'Reilly has said; another take on this is that users make all the content, but corporations keep all the revenue (according to Bash.org). There's a proliferation of pronouns (you, we, us), which opens an interesting tension of individual versus collective action (is 'you' singular or plural here?). Indeed, YouTube is a meeting place of so many different communities that talking about it in general misses most of the specificities of individual uses.
