For the past couple days, I've been listening to the back-catalog on Escape Pod, a podcast of science fiction stories read aloud. Most of the readers are podcasters with their own shows, and they've got good mic skills that makes the delivery of the material really sweet.
The stories vary from good to excellent, including a World Fantasy Award winner. Listening to this is like getting a great issue of Asimov's or the Magazine of Fantasy and Science Fiction delivered to your ear-holes. The whole thing is Creative Commons licensed, too.
I liked it so much, I sent the editor — Stephen Eley, whose introductions to the stories are utterly charming — my story Craphound for adaptation to audio (look for it soon!).
