After a couple months of trying, I spent two weeks in a Escape Pod marathon to finally catch up with Escape Pod and Pseudopod. I highly recommend it. I am breathless at the scope of the works presented, the skill of the readers and the visions of the authors.
Thank you to everyone for the consistently high quality of the authors, readers and editing - and this amazingly mature forum. I never regret listening, reading or posting!
As an aside, my first episode was "When We Went to See the End of the World" by Robert Silverberg and I found EP using iTunes.
