What incentive does Shaq have to whore himself on Twitter?

He's already accomplished so much in his basketball career, made plenty of money and even got to sample music/movies.

Is he one of those "never enough" guys, or does he simply like to hear/see himself talk?

My money is on the latter given his freestyle antics as of late.

/disclaimer: took Kobe's side in the feud, I think the media is in love with big Shaq and overlook his many warts.
