I strongly recommend the economic sociology blog, Estudios de la Economia, run by Jose Ossandon and Tomas Undurraga. One of the nice things about the interviews they publish is how they break the questions down, and upload each answer separately, meaning you don't have to dive into one vast hour-long MP3.
They've just published an interview I did with them a few weeks ago, discussing my book. It's the most theoretical and sociological discussion I've yet had about the book, and was provoked by some very sharp questions.
