We didn't have one in a while. What podcasts do you listen or listened and feel like recommending?
University of Oxford Podcast catalogue - Huge selection, seems like there's something on everything.
Fear the Boot - RPG and related topics. About an equal mix of side-tracked rambling and topical discussion, both are entertaining.
Exposing PseudoAstronomy - debunking crackpots and their theories in an informative, often in-depth if slightly technical, way.
The Arcology - All things Shadowrun.
Hardcore History - Can get rambly, but it's OK in the edutainment department.
Wolf 359 - Sci-fi audio drama. It's finished and doesn't really qualify as a podcast, but I felt like sharing.
Role Playing Public Radio - Another RPG podcast. I probably need a life, but if I had one I wouldn't be listening to so many podcasts.
There are also a few Polish ones, but IIRC no-one else speaks/learns it so sharing would be pointless.
