The AAFP announced two podcasts this week. One, a free CME podcast isn't exactly the most riveting audio experience, but the live panel discussion from this years' National Conference is a much better start.
The audio quality could be better, and the range of offerings isn't that great, but I'll always take the 'ship then improve' model over the 'wait until it's perfect and includes the kitchen sink' model (google Microsoft Vista for example of the latter.)
In iTunes, select the "advanced" menu, and then choose "open stream" or "Subscribe to Podcast" and past the URL of the RSS feed below. You can also search for the podcast in the iTunes music store podcast section.
