The only problem is that 90% of Silicon Valley startups are that kind of meringue and marshmallow that VC love. The record companies love Britney Spears and VC's love Twitter. It's all a big get-rich-quick scheme and a waste of time. Sadly, as a native of Silicon Valley, it means that true innovation, when it is happening, is occurring everywhere.
Besides, plenty of hackers do interesting stuff outside outside the open source world (and that's not even considering hardware...).
Nor are their investment choices what you think they are. For every frothy social app SV investors fund, they fund two boring b2b companies that you don't hear about because you are not the target market.
Fareed's comment is weird. Where is there a parking garage on Sand Hill Road?
Astons, bentleys, high end benz's... the works.
I work on Sand Hill and there's very very few garages around here. Just lots of open parking lots all over the place.
Also the culture here is to leave the fancy cars at home and drive a high-end (but not exotic) german car to work. In fact, tons of guys drive Priuses. Not too many bentleys - it'd be considered too crass.
