It's never clear how many people are replying to coal and how far the culture spreads among ordinary participants. I'm relieved the knowledgeable view is that it's a tiny minority. Some of the big fandom noms were weird -- someone really seemed to be arguing for Teen Wolf, of all things! At least those are easy to discount.

More explanation is always good, I think. It's easy to forget that there are newbies every year and not everyone is particularly savvy with AO3.
