Small subcultures are particularly aware of the ebb and flow of their community. They are fragile, and they depend on both a steady stream of new members as well as the retention of old members to stay alive. In her excellent article "Calling It Quits: Why Some Social Dancers are Hanging Up Their Dance Shoes", Mellisa West-Koistila identifies three reasons why the atmosphere of a dance scene might drive its members away. First, "faux professional dancers": the ones who are uninterested in dancing with less skilled or beginner dancers in favour of improving their own dance skills. Second, rivalries between dance schools or dance teachers. Third, boredom; dancing becomes less exciting, so dancers drift away from the community.
