To be fair to them, everyone is failing at this. Recommendation algorithms, once held up as a crowning achievement of machine learning, have turned out to be terrible at their jobs. Amazon, Youtube, Netflix. None of them have it figured out.
Spotifys algorithm is amazing, I'm constantly finding new indie bands that I love on it. YouTube is also really good. Netflix is terrible for me, I don't think it's ever recommended a show I've loved.
Huh. My experience is the opposite. Somehow my Discover Weekly was mostly mariachi bands for a month. Finally told it I didn’t like enough of them that it got the hint. Now it’s overloaded with Scandinavian adult contemporary or something. It’s like all the other algorithms from one I’ve seen: listen to something accidentally that’s in a niche and it just loads up on recommendations from that niche.
YouTube seems to be a lot better than the rest. I consistently get good music videos queued up, it is great for discovering new music
YouTube seems to give me clickbait crap with high view counts. Yes it may somewhat be related to my interests but not really.
