Forget privacy: you're terrible at targeting anyway (apenwarr)
The state of personalized recommendations is surprisingly terrible. At this point, the top recommendation is always a clickbait rage-creating article about movie stars or whatever Trump did or didn't do in the last 6 hours. Or if not an article, then a video or documentary. That's not what I want to read or to watch, but I sometimes get sucked in anyway, and then it's recommendation apocalypse time, because the algorithm now thinks I like reading about Trump, and now everything is Trump. Never give positive feedback to an AI.

Every service I use which has moved to “personalised recommendations/discovery” using some ML algorithm has gotten worse by doing so.

Every. Single. One.
