Medill Reports's Jason M. Breslow has a roundup of how Twitter is being used for politics these days. We're seeing folks use it to debate, to share ideas, to organize (though, as Jason mentions, we're not seeing either Barack Obama and John McCain use it to good effect). Witnessing the evolution of how people are pulling and shaping Twitter to fit their own political purposes is downright fascinating; What's most remarkable about the new Obama iPhone app is that it's actually the fruit of a relationship between the Obama campaign and a team of ten or so volunteers; The Christian Science Monitor's Ben Arnoldy asks the million-dollar question: can people-powered outreach really win presidential elections?; and quite a bit more.
