Andrew Sullivan has been embarrassing America's traditional mass media. With his one man blog, he has provided richer and more immediate insight into what's happening on the ground in Iran than even The New York Times. (I ask, somewhat facetiously, would we really miss the beleaguered newspaper industry if it went away? Not this week, we wouldn't.) Now Sullivan has pulled together an impressive list of tweets coming straight from the front lines. A short 140 characters can say more than you'd think, and, reading them, it seems fairly clear that the injuries, even fatalities, in Tehran may be higher than the MSM has reported so far. Right now, we're clearly seeing two new forms of communication -- blogging and Twitter -- hitting their stride.
