EscapePod - As you can imagine, EscapePod is a Science Fiction podcast. Most stories run about an hour long, and can be near future to distant future, to parallel universe!
PodCastle - Sister podcast to EscapePod, this one has a Fantasy bent to it, specializing in things in that realm, from elves to medieval fare.
PseudoPod - Another sister podcast to EscapePod, though this one I don't listen to, but if you're into horror, then this might be of interest to you, 'cause that's what they do!
And finally, The Secret World Chronicles - SWC is a miniseries by Mercedes Lackey and Steve Libby. It's a world like ours, where they've got Super Heroes! Not too crazy, and just enough non-serious to make you smile.
You can get RSS feeds directly from the sites, download the audio from there, or pick them up through iTunes, as you like. Enjoy!
