The Drabblecast is a weekly audio fiction podcast "bringing strange stories by strange authors to strange listeners...such as yourself." Founded by host and editor Norm Sherman, the Drabblecast is certainly influential and notable enough to have its own Wikipedia page, but it doesn't, because, man, that's Nerd Stuff, right there.
Drabblecast has a lot in common with Escape Artists - they share Norm, some editorial staff, a ton of authors, readers, and of course fans. In addition to regular full-length stories, they run 100-word fan-submitted drabbles and 100-character "twabbles", as well as original music by Norm and occasional guests. It's a lot of fun, and if you have any time or money left after supporting Escape Artists, you should definitely give the rest of it to Norm.
