*laughs* I frequently fandom shame myself in a whole "oh my god, brain, can we not do this, whyyyyyyyyyyyy?" but that's more of a "I don't have time for more of this ridiculousness, self" than anything else. Fandom has always been 100% self indulgent for me.

I find I'm a member of more writing communities than I am fandom communities (mostly because I end up... not joining fandom communities). This might come up later in snowflake anyway, but you might find fan_flashworks and ushobwri good communities to check out for general writing challenge/supportive discussion. I also like 1_million_words over on livejournal, which I use using the openID feature with my DW account (and have an RSS feed onto my reading page), since LJ and I have not been friends for a looooooooong time.
