>I moved from NYC to the Palo Alto area in May 2000. That's right, just one month after the start of the long stock-market collapse and two months after the NASDAQ's peak, although of course no one knew these things at the time. I thus got to experience both the highs (insane traffic on 101, Sand Hill Road absolutely packed for two hours each afternoon) and the lows (significantly-better traffic on 101--admittedly a good thing in and of itself--and hordes of people losing jobs and moving back home each month).
>It's important to distinguish between San Francisco and Silicon Valley. The Valley has recovered--traffic on 101 has long since become awful again, as today reminded me--but San Francisco still hasn't regained the equivalent of all those bubble-related jobs that vanished into the wind in the 2001-2002 time period, and probably never will. (I've been living in San Francisco for going on two years now and have yet to meet anyone who is working in a "Web" or "e-commerce" job up here. It's like a neutron bomb; the people went away but the buildings stayed.) By contrast, yes, the Valley lost tons of jobs, too, but at least the Valley had, and has, a longtime core of companies that made real products that do real thing dating back to the Fairchild/HP/Intel days. And on the Web side, of course, Google and Yahoo! are leading the charge. They're down there, though, and not up here. Unless and until another bubble develops, I expect San Francisco will remain a remarkably tech jobs-free (but with plenty of finance, retail, and other non tech-related companies) city on the edge of the world's greatest concentration of tech jobs.
Obviously I didn't know that there indeed soon would be another bubble in SF, this time a social media-driven one.
