What's on my iPod? Chances are I'm listening to something that's linked in the "Podrolling" section in the margin. Each entry has three links, in this order: the podcaster's website, the RSS 2.0 feed, and a link to the podcast's subscription page in iTunes.

That purple icon is the iTunes link. Click that icon and, if it's installed, iTunes will open and connect to the linked show's subscription and information page in the iTunes Music Store. (If you don't have iTunes, available here, you'll get an error message.) All of the subscriptions linked in my podroll are free.

P.S. My everyday computer is now running Redhat Enterprise WS (a subject for a future podcast), so I'm painfully aware that iTunes is not available to everyone. I'm experimenting with various Linux podcasting clients though (like BashPodder and iPodder Lemon), so solutions do exist.
