You know what I wish AO3 had? A way to exclude tags from search results and the latest works page. For example, I love Once Upon A Time! But there are certain characters that fandom (and the writers) seem to love, who I wish would die in a fire ::cough::Killian|Hook::cough:: If I could just go to AO3 looking for new OUaT fic and never have to see anything with him in it, that would be awesome. (I feel much the same way about Rose Tyler in Doctor Who. I don't mind her in the episodes she's in, but I get very annoyed at the way a large part of fandom writes her as if SHE IS EVERYTHING AND A FIC WITHOUT HER IS MEANINGLESS JUST LIKE THE DOCTOR IS MEANINGLESS WITHOUT HER.)
