Howard Rheingold has extended his study of virtual communities to the wireless space in Smart Mobs. He cites the fall of Joseph "Erap" Estrada as the catalyst for starting his book, in this interview.

Someone with a mobile camera - like the seemingly growing number of Nokia 7650 users - should consider putting up a picture blog like this one at Hiptop Nation. It's just an email to web conversion, so the magic is not in the tech but in the social experience.
