I recently went to a talk offered y the University of Hio TeachU series on PODcasting and it really sparked some interest in me. They were DEMOing their PODcasting setup and they also took the opportunity to talk about iTunesU. I've written about that before. I'm going to try to test iTunesU over the summer.... maybe with Janet's help (*grin*) and I'll let people know how I make out. If it's a success I intend to PODcast all my lectures this Fall (*smile*);-)
In the meantime if you need some reading on PODcasting, here is a nice Wiki that contains some great information on the topic: PODcasting on the cheap! You can even join this Wiki and contribute material yourself. Fun!
