Shaquille O'Neal will of course be remembered for his big frame and his gregarious personality, but he will also be remembered for his contributions to the social media space.
So it's not surprising that he became the first sports star to retire on Twitteron Wednesday.
I'm tempted to say that his adoption of Twitter is as big as his contribution on the court.
I always laugh when people say that I was one of the first sports guys on Twitter when I joined in March 2009.
Shaq joined in November 2008 and I think it's fair to say that, even though Twitter was getting big by that time, Shaq helped legitimize the space.
