The Valley is all suburbs, where people don't like that sort of thing. That being said, Palo Alto used to have a lot more homeless people, and more weirdness too. I can't imagine the Grateful Dead or Jefferson Airplane starting there any more. Yet still I live in PA.
SF has always had a much higher tolerance for weird behavior. Back when the city was a bedroom community for the Valley, people lived there (I did too) for its weirdness and culture. What happened with the dot com boom is that people who didn't appreciate the weirdness showed up, moved to SF, and then complained about it.
Honestly SF is a lot cleaner and safer now. Those whiners would not have tolerated the true weirdness.
