I can second Jon Galloway's mention of Herding Code, and since I have absolutely nothing to do with the podcast, with nothing to gain, my opinion may be more valuable than his :-).
There are only a few there as it's relatively new, but they are jam packed with good stuff that is very relevant to today's programming paradigms and strategies.
I also love the smooth format they've got going since 4 guys all giving input on a topic can make for a very jerky conversation with all (most?) of them dialed in, but whether it's the post editing or just a good format, either way it comes across as a very comfortable listening experience to the end user. Keep it up guys!
Hope that helps, Rob G
