I'd speculate that knowing/discovering/finding the answer to that question is at the very core of why he built the service.

I recently watched a 2005 guest lecture[1] by Zuckerberg, it hit me then, why facebook became the success it is/was. The core insight, was the "people you may know" feature, even though that's obvious when I say it, and think about it.. It never struck me before, that, facebook could have been anything (and, was indeed very different back then) and still have succeeded because solving that problem in a seemingly more efficient way at the time then nobody chocked on it.
