The only reason I signed up to Twitter was to follow athletes and reporters that tweet breaking news, transactions and draft info. I rarely tweet and don't even know if I have one follower other than my wife. I follow and read about sports from the athlete's perspective as well as the media.
All that said, there's a lot of fans who just thrive on being the internet bully to athletes. I've seen some horrid things said to these players that just make me wonder wtf is wrong with people. Anywhere from racial blasts to death threats. I admire some of these players to a certain extent for having the ability to screen a lot of this crap.
One other thing...I still don't understand the mental boner fans get from "retweets". "Retweet, it's my birthday" or "Retweet, I'm fighting cancer"....good grief!
