Fair warning, the HP fandom is HUGE, and things get pretty wanky at least 50% of the time, from what I can tell. I was lucky enough to be involved with it in only the most peripheral way possible.

That's one of the things I love about the RH fandom. We may have some (very minor) issues now and then, but overall, everyone gets along. There are no ship wars, there's surprisingly little wank, and there are no obvious BNFs. This makes me happy. :)
