Trying to do community by being welcoming and helpful, does have it's sense of cargo-culting

Er ... does it? I guess you can form community by deserting all the subjects on an island or something ...

edit: I just realized this sounds like I was trying to make a joke about cargo cultists living on islands, but what I actually meant was "well, how else would one form community, other than by being welcoming and helpful? I guess you could put a lot of people in a stressful situation together."
