I've listened to a lot of Stef's stuff. A couple of his philosophy "tricks" like the against me argument I find to be a bit cheap and specious, but there aren't too many intelligent libertarian voices that make a living producing content and commentary. Well, there aren't that many PERIOD.
Occasionally I wish he'd scale back his call-in show. Too often he tries to play the role as therapist, when what he should be doing is talking about philosophy as a whole, and not how it plays a role in the life of whomever might call in with a problem.
