Neighborhoods

After a couple of years on FB, I've decided their concept needs work. Someone ought to develop a social networking site built on the idea of neighborhoods instead of the open-ended concept of Friends. As long as it's not a gated community, why not build a site -- sort of what I'm trying to do here -- where people walk by, stop and chat, and head home. Neighborhoods are groups of people who live in the same vicinity. The vicinity can be defined broadly or narrowly. My friends and I can form a neighborhood through which people drive or visit for a while. Anyway, that's the idea.
