Who needs rolling commentary? It's usually drivel, in any case. What's important is the quality of thought and opinion of the participants (which may or may not shift your own views on important matters). On the IEA's offerings, the speakers tend to be highly intelligent and successful in their fields, while on QT they're mostly politicos with the votes of the greedy proles in their constituencies to consider. And 'poets', of course; experts in economics, taxation and policing etc.Looking forward to catching up with this episode soon. The shows are long but good. The format doesn't lend itself to rolling commentary like QT but it's a heck of a lot more informative.
