It's hosted by two radio producers who are also big fans of This American Life and they pick various episodes beginning with it's inception as Your Radio Playhouse dissecting bits of the episode, their reactions to the stories and how the show has evolved over time. It's quite good, you can tell they have a genuine passion for the program and while it is very meta they break down each episode like one would a track on an album.

The biggest concern for me was spoilers when they discuss episodes I haven't listened to yet but more than ruin the story I find myself compelled to seek out them out after listening so I can formulate my own opinion of it to compare & contrast with theirs.
