Didn't we already collectively agree that the events depicted in the Social Network were more Hollywood than Silicon Valley?
Not that I totally disagree with the comparison, I've made it myself as recently as yesterday, but it's not exactly a bad thing. There was a time when Hollywood was making a lot of good films. But those films brought in money, and money brought in vanity and all that other nastiness. There's certainly plenty of money bouncing around SV, but the fame is a bit more self-contained. If you move to the valley and send a letter home to your mom about how you bumped into Fred Wilson in a coffee shop, she would probably not run off to tell all her friends about it.
If the worst thing you can say about the valley is that everybody there wants to build something great and is willing to risk a lot to make an effort at it, that sounds like a fantastic environment.
