NYTimes’ Saul Hansell thinks Twitter might well be the birth of a media form that combines talk radio, Digg and late-night comedians.

“Like talk radio, you get an unvarnished and largely real-time window into what a wide swath of people are actually talking about. Like Digg, you see people point to the articles and videos that they want to share. And like late-night TV (or a politician’s sound bite for the evening news), there is a premium on pithy one-liners that try to get to the heart of the matter.”
