It's a good problem to have, I suppose--I'd rather have a bunch of stuff to post than not, but it does become rather time-consuming. And then I'll spot a typo in one place and have to track it down in the others as well. Sometimes I wonder how necessary the WordPress archive is, but I've had too many fics disappear on me as a reader to not maintain backups as a writer.
So. I hope no one's subscribed in all three places, because if so, you're going to get spammed over the course of the next day.
