Where in NYC? I find it really varies. At present in Bushwick, none of my neighbors talk or even make eye contact in the hallways, it is a pretty strange social situation. It is in pretty stark contrast to when I lived in Park Slope, where I would run into people in local bars, etc.

Yes, I live next to Prospect Park and I know faces of most of my neighbors (at least in the same 4-story building), and regularly 'socially interact' with some of them.

High density is one of the principal things I like about proper cities (like NYC or London or Moscow).
