I use YouTube for technical videos, and to gain other knowledge. And find the best signal to noise there than anywhere else on the internet. Occasionally, I give in to watch sports clips, movie trailers etc which is a decent short distraction. But do try to limit it, so the algo doesn't keep recommending those.

Recently, Youtube is pushing it's "Shorts"(Short-form video) in it's own section that you cannot remove, which is as addicting as you think it is, aside from that, the signal-to-noise is really favorable for me.

Compared to Twitter, Instagram, I find a lot more value on Youtube. The others I already used blocking extensions to stop me from visiting it. As sad and extreme as that is, it's worked out rather nicely for me. I occasionally need to check something, and circumvent it by going incognito, but mostly the blocking is helping me to redirect myself, and build better restraints, and habits.
