I used to like Rogan years ago. He was sort of like a cross between Art Bell and Howard Stern, but with less of a penchant for bringing on wild-ass cranks than Art Bell. I found Art Bell entertaining but didn't buy 90% of the stuff on there.

A real intellectual is someone with a deep understanding of their field. It's usually someone actually working in their field, not a media personality. Actually doing things generally leaves one with little time to talk about doing them, especially to the degree that is required to build a big audience.
