Weekend Confirmed, Garnett Lee's new podcast at Shack has hit it's stride and is quite good (drunk Garnett has yet to make an appearance, thankfully).
Slightly off-the-wall, but Wizards of the Coast have been posting a
new series of podcasts featuring Scott Kurtz of PVP and Jerry and Mike from Penny Arcade playing AD&D. Parts of it are drop dead fucking hilarious and although I don't especially like Dark Sun, it's still interesting to listen to (and has made me want to buy the new AD&D rule books, if only to have around for reading).
