Dave Winer is thinking of coming to New York:

Sorry to say it, but every other city in the US is small potatoes compared to the Big One. And it's starting to get an interesting high tech life. Over the last few months I've spoken with half a dozen high tech investors based in NYC, and I don't know what it is, but they seem more outgoing and business-oriented than the west coast venture guys, who somehow seem to act like they're the show, and you're an employee. In all my years on the west coast I never got one of them to invest in one of my ideas. Not once.

I remember running into someone in 1993 who told me that he was doing transactions for America Online and that Northern Virginia was already a high tech hotspot.  I was living in Washington DC at the time, and I was surprised. 

But I'm not surprised about NY.  As Dave points out, the city not only has airports and museums, but also has the Second Avenue Deli.
