^ Definitely. It's why I hardly ever get into fandoms to the point of actually interacting with other fans.
Just recently stuck my toe in the Adventure Time fandom within the last few months (and immediately fell in headfirst), although I've been a fan of the show since 2010. Big fandoms intimidate me, but I've met a lot of cool people so far.
v If you participate in fanstuff, do you prefer to associate with larger or smaller fandoms, or with a particular sub-group of a big fandom?
