I feel like short form video is inherently addictive, what special sauce are these smartest minds in the world using that adds to that?
I've never used it, but since YouTube introduced Shorts I've become victim to the addiction and subsequently blocked any trace of Shorts with a browser extension.
I think the way they make recommendations are pretty good (looking over my wife's shoulder sometimes). But that's just my guess, I mean, it could just be pushing the next best viewed video from the same tag.
