Some of them
I used to go out of my way to avoid any interaction with my neighbors. However, after the wife and I bought a house last year, I decided to make some effort to be more social and at least learn a few of their names. It helps that my neighborhood participates in the National Night Out, which kind of gives everyone an excuse to drink and hang out together once a year. The people I've met are pretty cool. We live in one of the more liberal, gay-friendly neighborhoods in the area, so my neighbors are a breath of fresh air from the lunkheads I work with.
