Twitter founder--who dropped out of college--now teaching M.B.A. students.

Christopher "Biz" Stone dropped out of college. Twice. Once from Northeastern University and once from UMass Boston. If he were in your class, he'd probably be the smartass in the corner that you hated because he laughed at your critiques of literature. (Like me!)

Then, as a two-time dropout, he went on to found Twitter. (Not like me!)

Now, according to the Wall Street Journal, he's a teaching fellow/adviser/new owner of a fancy name plate at UC Berkeley for their M.B.A. program.

Somehow this flies with educators.

It's like getting a divorce from your deadbeat husband because he cheated on you. But then you start dating him again because he drives a Benz and has a house in a desirable zip code. At some point you only have yourself to blame.
