True, but you eventually reach a point where your subscriptions fill your feed with more videos than you know what to do with.

I do branch out occasionally and find new channels to subscribe to, either on youtube or through other sources. Crossovers between channels are also helpful.

You can find new content by asking for channel recommendations on lemmy.
Fuck the algorithms, talk to real people. That’s how it used to work.

But you can search for subjects of interest, or ask interesting friends for their recommendations.
