This exercise just makes me wish I had an MP3 player.......
I checked out several different podcasts. I enjoyed the NPR sites and was happy to find that I could listen to Fresh Air online. I listen to it quite a bit on my way home from work and it's nice to be able to browse and listen to ones that I may have missed.
I also listened to Uncontrolled Vocabulary and enjoyed that very much as well. From a professional development standpoint, I can see where podcasts could be very useful. The isolation of my Western Nebraska location prevents me from attending a lot of meetings and workshops. It is nice to be able to listen to a podcast and get kind of caught up on what is going on in the greater library world.
As far as podcasting in the library, I think it would be a great thing to use (especially for YA's) for book reviews, what's going on in the library, programming, etc.... If I ever get our library website up and running, this is one of the things I am going to look into doing. I am not quite ready to do my own podcast, but after "22 things", I know I can do it!
