There could be an additional reason, that makes the community shrink:

Since the show "The Big Bang Theory", more girls could be interessted in Nerds and geeks and might feel attracted by them. So some guys now prefer to to pose "real life figures" instead of digital Poser dolls. That could be indeed very distracting. They might also feel encouraged to sign a contract in a gym.

In that case I'd see some runtimes rusting.  ;) ^^ :D XD
