Depends. Of course a small fandom exchange means "more fic for small fandoms". We agree on that. But you (or a coalie upthread? not sure if that's you) seem to think that the wider context and reception of the fic beyond what the recip wants should be something the author should take into account when writing the fic, and I strongly disagree with that idea.
