Really?
I've found him to be honest and sometimes cutting with his interviews.
Anytime someone is bullshitting or using weasel words he tends to call them out, if not directly then at least making them squirm.
Maybe you started listening before I did but I feel like I've listened to almost all of them.
Also +1 on Russ Roberts being a great host, I just wish there were more episodes with Mike Munger.
