I believe whats special in the Valley that I have not seen anywhere is the sheer concentration of startups, investors and qualified people and the willingness for them to share. Sharing comes in many formats in the valley of knowledge, their own startup, contacts and advise. The last two are the hardest to find elsewhere at the scale that you see in SV, I havent found it in Asia I havent found it in Europe... this for me is the competitive advantage of being in the Valley

There are probably more tech workers in SV than any other major metro area
