According to the Startup Genome reports, it's considered #2 startup scene (NYC is #3)
But at the end of the day it's still Silicon Valley #1 by a long shot... and then everyone else duking it out for #2. I don't see a reason to believe the status quo is going to change overnight. Culture tends to shift slowly, and culture is one of the best things SV has going for it.
I suspect that this is not sustainable.
