And I'd argue that that is really all you need. It doesn't really matter if the old people aren't interested in trying new things - the new people will bring new things, and maybe some of the old people will find they like them, maybe they won't, but its all good. Tradition is fine, as long as you can make new traditions. If people don't want to try new things, that will usually break down pretty quick once the people who do try new things start seriously having fun. It doesn't matter if the individual people are somewhat conservative, as long as the institutions are not.

Sadly, though, most fan clubs are deeply conservative institutions.
