I work for an SV startup that has a satellite office in Seattle. We're in Seattle for the engineering talent. I think Seattle's role in the startup world has a good foundation because it's about talent. As for NYC I can tell you what the founders say around the office. That is that the foundational tech doesn't come from the East Coast. The business culture is aggressive and well financed but not as innovative in tech as SV. This has lots of downstream effects. Incorporating leading edge tooling is faster in SV for example. Learning from failure is a norm not an embarrassment in SV. Fundraising means driving to SF and Menlo Park, not flying. It's easier, more networked. Etc. At this point SV's advantages compound each other. What will happen is that SV will spread to Oakland and Berkeley, the next frontiers.
