A friend of mine keeps saying that it's incredible how well TikTok's personalization works. I'm not on it, and his descriptions make me not want to be. I'm not looking for another time sink.

I guess I agree with you on YouTube, as well. I have mentioned a video to someone by starting with "I don't usually watch YouTubers, but this one..." so often that the disclaimer started sounding ridiculous. They were very good at luring me to some exception channels that I would like.
