More data beats better algorithms, and Tiktok gets a lot of signals about what you might like based on how long you watch, how many times you watch, what you like, what you comment on, if you go to the profile page of a video you just watched, if you share, etc. Multiply that by all the videos you can see in a single hour, and Tiktok learns more about you than YouTube has in the past 5 years of use.
Absolutely not - I was using youtube for 10 years and every year my feed gets worse. Now the original content creators are dissapearing from my newsfeed and uts fetting invaded eith short clips of family guy. Its also will show me same clip again and again. It shows clips from creators i disliked. New uploads of creators i follow sometimes arent on my feed - its a shitshow. Half of comments are trolls and bots.
Holy crap literally this happened to me few days ago
