Using YouTube shorts myself I think the reason is that the algorithm is a bit janky. I notice that something it’s fond of is to continue pushing me these clips from podcasts hosted by random comedians (I’m sure you know the type of content I’m talking about.) probably because lots of that type of content gets generated every week. Sometimes it’s funny, usually it’s not, but it’s not something I swipe away from immediately. I think that these types of videos are pretty strongly linked to the right wing talkshows that follow similar formats. The algorithm just assumes it’s all similar content i.e. white men talking. I guess it’s just a speed run of the famous “alt-right pipeline”.
