Emergent democracy examples sought

Joi Ito is soliciting examples for … Emergent Democracy Worldwide discussion, and the commenters include Craig from Craig’s List (“I’m involved with the San Francisco 311 program, which I’m treating as a genuine opportunity to reinvent government. …they sound real“) and Jeff Jarvis from BuzzFlash, who points to Hossein Derakhshan’s Editor: Myself blog in Iran and the way it has spawned tens or hundreds of thousands of blogs there.
There are other good examples worth following up in the other comments.
So far, we are talking about international examples (Eastern Europe, Middle East, Asia, etc.) in the main politics chapter, but I wonder if there might be enough material for a separate chapter?
