It's been an interesting few days for athletes on Twitter, the popular social media and networking platform. Kobe Bryant, a longtime Twitter holdout, joined the service and picked up more than a half-million followers overnight, then quickly began using Twitter in interesting ways. Texans running back Arian Foster has been a longtime Twitter user and changed his avatar to make note of a column critical of the Texans.

And is Twitter good for athletes? Cast your votes!
