Well, thanks to my Bloglines account and to my husband, who turned me on to Dan Gillmor, I found this great intro to podcasting. It is a video that takes you through the steps. It was really easy to download and to set up. At the moment I am listening to "On the Media" from NPR.
I would never have believed I would get this far into all of this. But it is amazingly easy. And there is so much out there!
