Have I offended anyone yet? Not my intention. My point is that we don't see a lot of transporting of CTOs between the coasts. But I love it every time I get to visit and do business in San Francisco/Silicon Valley. I have the same experience each time, technology rocks there. What I find myself doing is figuring out how to take West coast learnings back to the East coast. There's an easiness/flow to technology development on the West coast which is hard to find back east (along with a little more risk-taking).
As an East coast CTO, you should take every chance you can get to visit the West coast. My first-ever US trip (in the 80s) was to Silicon Valley, and that was my main reason for deciding to move to the US. I "missed" my mark and landed in NYC, but no regrets.
And talking about moving coasts, I am extremely happy to announce that New York got one of its finest back recently, Curtis Brown, the new CTO at Kaplan Test Prep & Admissions (my previous job), formerly CTO at McGraw-Hill/CTB in Monterey. Curtis is the quintessential New York CTO who combines tech know-how with business-savvy. Kaplan will excel under Curtis, and we New York CTOs welcome him back to "our" coast.
