My co-founder and I live in Berkeley, so the center of gravity of our new company will be in Berkeley.
I kind of love that.
We're adjacent to Silicon Valley, but outside it.
Whereas Silicon Valley emphasizes tech and hyper growth, Berkeley emphasizes holistic approaches, organic growth; understanding of the implications in the broader socio-techno system.
Berkeley has associations with Unix, counter-culture, hippies, Christopher Alexander, etc.
Although the hacker ethic and things like Whole Earth Catalog grew out of Silicon Valley originally, Silicon Valley has matured and become more traditional as the tech industry has matured, and Berkeley keeps alive more of that energy.
