Every dialogue that I have listened to has been interesting, engaging and enlightening. Duncan manages to be very interesting and insightful in his own right without ever overshawdowing is guests. That, my friends, is a true talent. I have not listened to a single conversation that was not informative and interesting. I haven't heard of many of the people featured, so I never know what to expect; I have no preconceived notions; I have not been disappointed with a single interview. I highly rec. this podcast!
