I ranted before about Car Talk using Real Audio as their only way to listen to their show free online. I found out today that they are now offering a way to download an mp3 or go through Itunes for free. This will be much more conveinent that having to install Real Player and all the adware and bloat that installs.
The link to the RSS feed that allows you to play or download the show is http://www.npr.org/rss/podcast.php?id=510208. It looks like NPR is putting several of their shows online
