The advantage of podcasting is that people don't have to keep checking the page for updates - you can just set your software to download a new podcast whenever one arrives. Of course, as Doug always sends an email when he puts up new radio shows, we all get notified of them anyway.
Incidentally, I've seen a reference to an easy podcasting system at http://www.shadydentist.com/wordpress/software/dircaster . Apparently, all you need to do is put one file in a directory on the server with your MP3s, and it will create a podcast feed from them automatically.
