I agree with Art. It's nice to be out of the mainstream, and to be able to do my own thing even if it doesn't fit in to the pop culture (or maybe because it doesn't). What I think is important is to have a critical mass - that might be anywhere from just two to a few dozen people, depending on the locale. And also having a few young ones to take over when the old guard passes on.
