I listen to the Adam Carolla podcast, and a few brewing podcasts like Basic Brewing Radio, the BeerSmith podcast, and if I'm really desperate for something to listen to, TBN Presents the Jamil Show. I really want to like that podcast, but it's just soooo terrible. It's waaay longer than it needs to be, the commercials are obnoxious, they take forever to actually get to talking about the beer that's supposed to be the topic of that episode (you can safely skip over at least the first 10 minutes of every episode, as it's just pointless, inane banter and crass, juvenile sexual double entendres), and then when they finally do actually talk about the beer, it's really at such a cursory level as to be almost useless. They don't go into its origins, sample recipes, tips and tricks about brewing that specific style, etc. They just read the BJCP description and sample a couple commercial examples, comparing them to each other.
Jamil is an icon in the brewing world - I really wish he had a better podcast. It feels like such a waste of his abilities.
