Check out
-A rather unconventional introduction to New York
-The comments on the ins and outs of NYC in Jason Kottke's weblog.

If you like the city, Both make for fascinating reading.

I am hoping to check out the following whenever I go to New York next:
-The Winograd exhibition in ICP
-Liz Deschenes show in Bronwyn Keenan.
Aperture exhibitions.
