Podcasts--endless confusion.

Well, our 21st assignment is to look at podcasts. I have to admit, that this one is pretty confusing. I tried to find library or Darby related podcasts using online directories, to no avial. So I ended up subscribing to Car Talk podcasts! But at least I understand how podcasts work, how to search for them...and at least I don't have to worry about missing Car Talk any more!
