I only watch the full podcast when he has guests that interest me. For me that mostly means people with knowledge about health, fitness and some sports. Now, that too can be hit and miss depending on how clued in the guest actually is. As I said, the podcasts with Rhonda Patrick are absolute gems because she really, really knows her shit. And she doesn't speculate when there is stuff she doesn't know.
Youtube is full of snippets where Rogan and his guests make no sense, but IMO that has to do with the guest being full of shit more than Rogan. I've never heard Rogan claim he is an expert in anything other than martial arts, and from my knowledge he has not claimed to speak about other stuff from any sort of place of authority. He could choose his guests more carefully of course! Then again it is entertainment, he is in it to make money, and the crazies attract followers and revenue. Meh.
