Hoping to revive its waning brand with the college set, Playboy is set to launch a new Facebook-like social networking site named "Playboy U." Playboy U is said to have many features similar to Facebook, but is focused squarely on college students only -- admitting only those users with ".edu" email addresses. Which begs the question -- will provocative message topics like "What Do You Think of Penis Enlargement?" really be enough to make Facebook users leave the fold?
Seems like a tough sell to me.
