When Kobe tweets, we get fun little looks into the life of a guy who is one of the most private superstars in the NBA. When Scalabrine tweets, it's another outlet for him to interact with his legions of fans, and dole out a joke or two.
He's exactly as you would expect him to be—having fun with his fans, interacting as much as he can and being altogether goofy while not specifically meaning to.
All that, plus you get a look at the highlights of his career from time to time, which is definitely a nice thing.
Of course, we get to see when and where he's going to be on television or the radio, because we all know very well that no amount of Scalabrine is too much Scalabrine.
