Nima Shirazi and Adam Johnson’s podcast Citations Needed is one of my favorites; they never fail to illuminate their topic, and their research appears to be impeccable. I also like the slightly unsophisticated un-slick audio and editing; podcasting is metastasizing into a big business full of well-funded corporate drones that milk advertising opportunities, so it’s refreshing that there are a few hold-outs that stay resolutely old school. They’re just about the information.
