Great list man. I’m personally offended that The Gently Mad isn’t on your list. 😉 Just kidding.

Another great podcast that fits right in with the shows you mentioned is Sean McCabe’s podcast (http://seanwes.com/podcast/). Sean does a terrific job thinking deeply and thoughtfully about life as a creative entrepreneur. I’m regularly blown away by the quality of each episode (and he does two a week!).
