I really like Joe Rogan, and the format of its podcast. I don't know other medias where they let people speak for three hours. I was suspicious the first time I listened to him. I thought, can this beefy archetypical MMA dude say anything interesting? actually he can. He's at ease with all types of guests, he just seems to be an outspoken, honest guy.

I agree that he tends to bring up his favorite topics all the time, which gets a bit repetitive but it's ok. You can't expect him to run hundred of conversations without being repetitive.
