Dropping by this thread to plug another interesting new comm, queerlygen, which is for fic that's about queer characters in non-romantic/non-shippy situations. Their profile includes "asexual" explicitly, for what it's worth, and I think the mods and comm members seem to definitely support asexual inclusion. I've been lurking there so far, but I'm definitely developing a couple of ideas with an eye to posting to that comm, because it's pretty great.
