I joined AO3 because of Yuletide, and I keep meaning to archive the rest of my stuff there, and then failing to do so. I feel like fic gets more attention in archives, and is easier to find. I'm still getting notices on my Yuletide fics months after the fact, where, at LJ, within a week, there are no more comments. (Maybe this has something to do with the fic being part of an exchange, maybe I've rambled enough already.)
