[Does GRRM know there's still an active Beauty and the Beast fandom?]
It doesn't surprise me that there is still a B&B fandom, no.
In fact, I think there's two. The ones who embrace the entire series, and the ones who insist on "44 and No More." Are they still at war, after almost twenty years? I hope not.
I don't think either one is as large as it once was, but maybe I'm wrong.
