Agreed. Youtube recommendations are genuinely great for me. Most of the time I'll be recommended so many more good videos than I have time for, that my "watch later" playlist only keeps growing.

Compared with, say, Netflix, where even though I've been rating everything I watch on there for 5+ yrs, the recommendations still barely feel personalized (if anything, it feels like it personalizes which premade "top list" to show me, but not the titles within them...but it does personalize the cover art/thumbnail, lol).
