The problem everyone is complaining about is that they used to recommend a good mix of content that was actually relevant. Like if you were watching a bunch of comedy videos by one comic it would recommend more of them but also another comic that you would probably enjoy. I don’t know how they did it, maybe it was just based on what other people with similar demographics and interests watched. If it was then they probably broke it when they decided to pop the filter bubbles. Turns out some of those bubbles were useful, they just decided to throw the baby out with the bath water.
