Yeah people have mixed opinions about that, but atleast in my case YouTube's recommendations does a really good job at finding content I'm interested in. It just needs some training for it to do a good job. When there's something I'm not interested in, I just flag it as "not interested" and then that stuff dissapears and is replaced with something else.

I don't agree, you need a way to discover new stuff (akin to going to /all). What I do hate is how they don't give you the option to do anything but that. Or they give the option but it's incredibly annoying so you don't use it. Like you can't trust YouTube to show you the content from the people you're subscribed to. You can't trust them to even show their content on the homepage of the channel if you want to be sure you didn't miss anything interesting you have to go channel by channel clicking in the videos and live tabs for anything the algorithm might deem not worthy

I follow way to many creators to have a sensible subscription feed, especially when I only watch some videos from some channels. If there were tiered subscriptions, I'd use them more. But right now I only use subscriptions for my tier 1.

I couldn't live without my Spotify recommendations. Being able to listen to new stuff everyday is so important to me.

I'm the same way, I watch (hate to admit) hours of YouTube every day. I do subscribe to a lot of people, but only after I've seen several of their videos and enjoyed them. Primarily I refresh the homepage and see if anything peeks my interest. In my personal opinion YouTube has one of the best algorithms, generally showing me a good mix of stuff I'm interested in (with addons and whatnot to hide the bullshit and recommended MSM garbage). Conversely Instagram and Facebook have some of the consistently worst algorithms, but I think Facebook is getting better about it, Instagram however NEVER shows me ANYTHING I could ever possibly care about and usually actively get annoyed by.
