Wikipedia: Good Faith Collaboration?

Cory Doctorow  review of Joseph Reagle Jr's Good Faith Collaboration: The Culture of Wikipedia.  Many people now depend on Wikipedia for better or worse.  How does it work at all?  I have been peripherally involved in examining some edit wars and vandalism there.  What I saw was not good faith, but obsession with a version of the truth.   Read also some of the comments, which give other examples of why it should not work.  Yet it does for most people.  On order.  See also, the book's site.
