My interests vary so widely that my home feed is awful. I like watching videos on power tools, software development, video games, sports highlights, math, and other, less focused things like the hoard of cat video channels I sub to to keep existential dread at bay.
I get recommended right leaning videos and videos with ads for manscaped and I'm neither a conservative or a man. It's super weird so I tend to separate my interests into two apps: the YouTube web app for "junk food content" and FreeTube when I want to learn and focus. It's the only way I've found to not be fed the random content carrots while falling down the rabbit hole.
