Brief is the ticket. The more you hot ot not it, the better it gets at matching you. After a couple days of swipes, you'll get a constant stream of stuff you'll actually want to see. IG and TT are good at this, yt shorts are pretty bad at it.
I've been trying to stay out of the algorithms. I watch YT by channels only, left Reddit for Lemmy, listed fb to friends walls. TT and IG only make it to me if friends or family share it. I'll go watch it then GTFO.
