AJR: Is Twitter an effective journalism tool?

“It’s okay to be sick and tired of Twitter,” begins “The Twitter Explosion,” a recent article from the American Journalism Review.

But for journalists, the piece goes on:

“…the real question is whether Twitter is more than just the latest info-plaything. Does it ‘work’ in any meaningful way — as a news-dissemination channel, a reporting and source-building tool, a promotional platform? Or is it merely, to buy the caricature, just a banal, narcississtic and often addictive time suck?”
