So I just started listening to FOAMcast [link is to the web page with the show notes for all of the episodes (14 pages at the time of this post)].
If you want to start at the first podcast and listen sequentially, then go here to the bottom of page 14 for the show notes.
For direct links to all the mp3 podcasts start here at page 2. This page has direct links to the mp3s of the first 22 episodes.
For direct links to the mp3 podcasts from episode 23 to the current episode (episode 90 at the time of this post, go here to page 1.
I have just listened to the first four podcasts and they are very useful for my practice which is a primary care adult and pediatric practice outpatient practice.
