If you haven’t seen Daily Science Fiction yet, they’re publishing some great stories. You can read them at their website; or, if you want the stories when they first come out, subscribe to their mailing list, and they’ll e-mail you a new story every day (they publish both science fiction and fantasy).
I have to admit that I don’t read every story that shows up in my Inbox. Maybe if I had more time. So far I’ve especially liked Therese Arkenberg’s “The Fosterling” and the current featured story, Matthew Johnson’s “Long Pig” (for anyone who’s an afficionado of fine dining).
