>Rogan's not really a great moderator (for example, he doesn't even read the books of his guests). He's not asking insightful questions. He can even be a bit dense. But he's open-minded, curious and "normal".

I don't really like Rogan personally but this behavior is intentional and quite smart in my opinion. Rogan (and his team) preps quite a bit, the vibe he is going for is an everyman who does not know anymore about the situation than you do. This is not reality. The idea is that this style makes the listener not feel stupid or embarrassed to learn about the viewpoints of the interviewee. He's among the most listened to interviewers in the world, so I guess it works.
