I do both! It's really fun and easy to happen in the union square area.
That said, I find myself have so many tech company comvos in NYC that I'd not want to have any more tempting me. That said, fun techie convo and hangouts at the high end of the spectrum (the only sort of tech folks I enjoy having as good friends) are a bit sparse, but they're sparse population wise everywhere (though the absolute number of folks in that possible pool is likely larger in the sf area. )
I must confess that the large population of young college grads who are neither engineers nor dudes is also a fun attribute of union square area
