Casting with a pod not a rod

I thought this was a new version of fly fishing? Podcasting is an audio format that can be downloaded onto an ipod or MP3 player. Just think - you can download a lecture and listen to it while jogging or doing dishes. Something productive! Check yahoo podcasts or podcasts.net or itunes store to download. You have to set up the proverbial account but what did you expect? Think of a podcast as an extension of your own personal radio station. I think I would really like this. It's like being read to - something comforting in that!
