Bill Simmons:
Twitter, which exacerbates the demands of immediacy, blurs the line between reporting and postulating, and forces writers to chase too many bum steers. With every media company unabashedly playing the "We Had It First!" game, reporters' salary and credibility hinges directly on how many stories they break. That entices reporters to become enslaved to certain sources (almost always agents or general managers), push transparent agendas (almost always from those same agents or GMs) and "break" news before there's anything to officially break. It also swings the source/reporter dynamic heavily toward the source. Take care of me and I will take care of you.
From great article on the accidental Tweet
