No Agenda is a great show, but it's biggest downside is the fact that so many of the stories discussed are long and ongoing, making it hard for a first-time listener to jump in. That's why Adam and John did episode 200.5. It was meant to be an introduction to how the show works and all the little peculiarities.
Recently, they re-released it as #200.8, combining episode 200.5 with updates and a bit of a commentary on the commentary. If you're interested in No Agenda's media deconstruction, but don't know where to start, this is it!
