Basically they do, is the bad part. After my last convo with Branch about this, the metaphor occurred to me that being a tag-wrangler is like herding cats, except that you're required to wear an invisibility suit and not allowed under any circumstances to actually pick up a cat and move it.

OT, in an uncharacteristic frenzy, I actually adopted 5 new fandoms the other day, and it was actually kind of fun, admittedly, but I shake my head because on three of the five the first thing I had to do was change the canonical name of the fandom; on one it was even requested by staff because Ao3 apparently can't recognize an O with a macron on it as an O and alphabetize it accordingly... -_-;;

At least the person who wrote that sweet Hyouka fic had all the ducks in a row and I just had to canonize everything...
