I've been thinking about this, but I don't really know. The podcast is a lot of Clojure, which by itself might be an interesting language to learn. Some people report that learning Clojure was different than other languages, eg Uncle Bob, Gene Kim (see "Love Letter to Clojure") or I think even Paul Graham.

Maybe the Effectively Isolated Serie might be interesting (ep 021-027). Oh, and Cooking Up Composition, about composing functions (ep 093-098).
