The best part about tech in NYC is that it isn't a non-stop, in-your-face bubble the way that it is in SF/SJ. I work in tech but enjoy having friends in fashion, finance, real estate, advertising, etc. The conversations here are much more diverse. Interestingly, that same diversity helps improve the tech sector.
There's definitely a trade-off -- while it's nice being exposed to the issues people experience in a variety of industries, it was nice having easy access to engineers/friends willing to hack on ideas in SF.
