Yep, I was just thinking the same thing. A lot of the "hot" startups are actually in San Francisco itself so may want to take that into account. Beyond Silicon Valley proper there are companies scattered throughout the Bay Area region also.
I'd second that. You want to say in the Bay Area. Also as a young person SF would be a lot better for him than Palo Alto. Palo Alto and the South Bay is a suburb where developers go to start their families.
this site was originally designed for one startup from Palo Alto.. but since it's here on HN, I'm really opened for everything in Bay Area :).. i've got some first offers already which is awesome :)
