As we mark Twitter's fifth anniversary, it's a good time to acknowledge the social media site's influence on the sports landscape. Every NBA, MLB, NHL and NFL franchise has a Twitter presence and its impact on news has been profound, as SI.com's Jon Wertheim reports in this story. For SI.com's inaugural Twitter 100, we polled more than 50 Sports Illustrated staffers -- from reporters to writers to editors -- who are hard-core Twitter users and asked them which feeds they considered essential to their daily routine for finding news, information and entertainment from the sports world. We gave them one guideline: You could not choose anyone associated with SI or our main Twitter feed (@SINow). After weeks of debating the endless possibilities, we've whittled down the list to our top 100, which we present in alphabetical order (click here to view by sport).

*Of course, we know this list is subjective and we want hear from you about who we left out and where we screwed up. Weigh in with your thoughts here.
