I am not new to podcasting. We listen to certain podcasts fairly religiously in on our iPod in the car--NPR's Sunday Puzzle and A Way With Words.
In searching out some new podcasts, I discovered a blog that has a post that lists numerous links to, what else, Jane Austen Podcasts!! HURRAH!
I looked at some of podcasts the author lists and found one from NPR when they intereviewed screenwriter Andrew Davies on Morning Edition about his numerous Jane Austen adaptations. It was from the Morning Edition: Interviews portion and I added that feed to my Google Reader account. I also have Nancy Keane's booktalks podcast feed in my GR account as well.
I think iTunes is so simple and easy to use. I did do some exploring in PodcastAlley and Yahoo Podcasts, but I am partial to iTunes.
I have tried podcasting on my media center website for bookreviews. I have published 1 and have 1 waiting in the works. (I just need to sit down and take the time to finish it.) I am trying to get some 8th graders to do some book podcasts with me, but they just aren't biting at it right now. I think the only way I'll get them to try it is if it is with or for a class activity. Here is the link to my podcast, which I made using the software GarageBand on my computer. I have also played with Audacity.
