Potterrific Podcasts
Endless Discussion
Podcasts: It's like having friends, but without the effort.
MuggleCast:MuggleCast is the official podcast of the HP news website, MuggleNet.com. It was one of the (if not the very) first Harry Potter podcasts out there. They have been on the air for over a year, updating weekly. Regular hosts Andrew Sims, Ben Schoen, and Jamie Lawrence (among others) discuss recent HP news and theories about what is to come in the series. And they're really funny (in a totally dorky sort of way).
PotterCast:
PotterCast is put out by HP news site, The Leaky Cauldron. Like MuggleCast, the PotterCast hosts (Melissa, John, and Sue) discuss news and theories, but PotterCast is much more structured. The show is broken up into segments including, but not limited to, Sue's News, Canon Conundrums (with guest host Lexicon!Steve of the HP-Lexicon), fan interviews, and Extendable Ears (interviews w/people involved in producing the Harry Potter books, movies, etc).
SnapeCast:
So Snape, he's an interesting character. The SnapeCasters sure seem to think so! This podcast is dedicated entirely to the greasy, is-he-good-is-he-bad potions master. In each episode they discuss any Snape-related news and discuss different aspects of his character. The show also includes skits, top ten lists, etc.
LeakyMug:
The LeakyMug is a joint podcast between MuggleCast and PotterCast. It was initially created when both podcasts were taken off of the itunes feed over feuding rumours. Basically the point of the podcast was state that no, there is no rivalry between MuggleNet and The Leaky Cauldron. They're buds. Since then, the show has morphed into a joint podcast that records live with a fan audience at various Harry Potter events (movie premieres, conventions, etc).
