I’ve been experiencing this same thing for a while on YouTube and thought it was very peculiar.
I have 2 theories:
It’s intentional; YouTube figured out that people like me have just blocked all the mainstream channels like Fox, (even though I like Fox) just to get around the flooding of recommendations with MSM channels; and thought that Joe Rogan is the next best thing.
It’s automated; and the algorithm goes off the variable of watch time; in which case Joe would standout because longer podcasts coupled with millions of views.
PS . I like Joe Rogan , but I too thought it was odd that he’s constantly being recommended after every video.
