I listen to a few at work. I've had aTorch in my hands fora good part of the day the past few months. Instead of wearing ear plugs, I've had ear buds in and have been listening to the Profire Arms Podcast (Massad Ayoob), The Gunfightercast, The Survival Podcast, Common Sense and Hardcore History with Dan Carlin and Downrange Radio with Michael Bane. I tried listening to a few others like Guntalk with Tim Gresham and the Gundudes, but just couldn't handle them.

Anyone listen to podcasts? Have any suggestions for others? I also recently discovered iTunes U and have been listening to a class on revolutionary era America from Joanne Freeman at Yale. Pretty interesting stuff!

I have a subscription to Rush Limbaugh's site just for the podcasts. I can listen to his 3 hour show, without commercials, in about 2 hours.
