What podcasts does everyone listen to? What are your favorite ones -- any recommendations?
I really like This American Life and discovered 5by5 the other day. TAL is great by me because I love stories, 5by5 because it's a tech podcast and, well, I love technology.
This American Life has a great app, which let's you go back and listen to (or save) many programs from their archive.
There is a podcast of a local southern California radio program, KPCC's Air Talk, which I highly recommend. A wide ranging interview program, with regular coverage of tech and science and interviews with film critics on Fridays.
There are a number of ways to get TWIT programs, various apps and iTunes. In addition to Tech News Today, Macbreak Weekly, This Week in Tech, and others are quite good
I also like the Mac Power Users podcast.
For history, I enjoy the Bowery Boys New York City history podcasts.
I would also take a look at iTunes University to see if there are any tech podcasts there that might interest you.
