As part of my ongoing effort to join the 21st century, I bought an iPhone several months ago. Now it's finally time to make some use of it. As it happens, I walk up to the market every day to buy food for dinner,1 so I'd like to start downloading podcasts to listen to on the way. Yesterday, for example, I listened to the Ira Glass retraction of This American Life's Mike Daisey story.
So: any recommendations? What are your favorites? I don't listen to the radio at all, so feel free to recommend anything. Or how about class lectures available as podcasts? Have you come across any especially good ones lately? I'm open to anything, but the ideal recommendation will come in approximately one-hour chunks and be free.
1Why do I do this every day? Because it's a good way to force myself to get outside and walk. I'm a lot more likely to do this if I actually have someplace to go, so unlike most people I buy groceries daily instead of weekly.
