Thanks for this post - you've addressed a subject I've been thinking about for a while; that being the definition of 'belonging' to a fandom. I'd never considered myself capable of being multifannish until I recently found myself with one main fandom and several minor fandoms, and I've recently come to the conclusion that I was right all along, I'm not cut out for that at all: my 'minor' fandoms are media I enjoy the hell out of and consider fic for and talk about, but simply don't eat my brain the way my 'main' fandom does. For my other interests I don't read meta, and I skip clicking cuts, and I don't force my way through awful fic just because it features my pairing. And trying to be multifannish has done nothing more than split my concentration and screw with my ability to write fic. So. Epiphany. :-)
