I only post stories to AO3 right now, although that's mainly a product of the fact that I've only just returned to using journal sites after several years of absence; I used to have an archive on LJ & haven't reached a decision about whether to reestablish something like that or not yet. So yeah, AO3 is the obvious place to watch for further stories at the moment, though I also post links to any stories there from my personal journals on LJ & DW.
