AO3 (Archive of Our Own) now supports subscriptions. Talk about awesome!
I'm at HalfshellVenus over there, and what I mainly have posted is all of my random-fandom stories plus a few character-of-color POVs for Supernatural. There'll be more to come in my random-fandoms (Die Hard 4, Iron Man, Chuck, Burn Notice, White Collar, Fringe, House, 24, Terminator:SCC) over time, and I'll eventually get some of my Supernatural and Prison Break stories up there.
Here's a question for all of you: of the painfully many stories I've already written for SPN and PB, which ones do you think I should put up at AO3 first?
