This is essentially what college campuses do already, to some extent. My current apartment complex also hosts activities, movie nights, brings in nurses so residents can meet and ask about health problems. This is in addition to the playground, tennis/basketball court, computer room, gym, small theater, and other amenities that help to create a "community" atmosphere. Also, I think a big reason this model is so "successful" is that people don't have much of an alternative. Really, would you _prefer_ to go to that sketchy-looking grocery store with the mayonnaise next to the cereal, if you had the choice of going a few blocks to a large supermarket? To be honest, I've never spent any time using my own apartment's amenities. I live in the city, because I want to be with people like me, not because I want forced socialization with people who just happen to live together.
