It usually doesn't happen. But if it's something that is big enough to be national news and everyone's waiting on, like Darvish, it gets ridiculous. The night before it was announced I was following and just hit yu darvish in the search. Every few minutes, some other team supposedly officially won the bid. So you went to see what the entire internet was saying and you were surprised it was conflicting? This is amazing. All I really follow as far as sports news goes on Twitter are MLBTR and Bruce Miles and as of recently Kevin Goldstein. I usually use the search. If for example you typed Pujols in the search box the night before he signed you'd ge multiple reports of if and with whom he had signed. Aside from Miles, MLBTR, and Goldstein who are some good ones to follow for such things? Again, you're still surprised when you looked to see what the bajillion people on twitter were saying and it was conflicting? As for the best twitter writers I'd say just the guys like Rosenthal, Bob Nightengale, Stark, Olney, Jon Heyman and Knobler would probably have you covered.
