Wow! There's a whole lot of information out there on almost any subject you can think of.
Since we aren't allowed to download any software to our workstations without permission, I used the PodcastAlley directory and found a podcast on quilting to which I subscribed. The book review section has a category for any interest. You could use podcasting in so many ways, keeping up with what's current, information on topics such as health and news, you could even put programing and events on a podcast, the uses are almost endless.
