Facebook has in a lot of ways run its course. They're still iterating, but I don't really see it benefiting users much.

I don't see a sale to Apple benefiting users much either, but the fallout could be interesting. If I were him I might sell just out of curiosity to see what would happen. It sounds, if not better, at least profoundly interesting.

It doesn't... but the chance to work along side one of your idols is a pretty big factor.
