Watched some Nightcore, and immediately half of the recommendation list is full of it. Not that they are useful anyway, as I've seen the other videos displayed there already.
Random stuff, I don't even know why YT has been recommending me Elite: Dangerous videos for a few weeks now even though I haven't played and searched about the game for more than a year.
Some things make sense and are of channels I watch, like Military History Visualized and Tom Scott's channel.
It was a while ago, but at least on mobile it feels like it sometimes loses track of what my profile looks like and starts recommending me Minecraft LPs/Overwatch/random viral videos and other stuff I'm not interested in. And yeah, I mark it all as "Not interested".
Watching my usual subscribed retro gaming channels, but also I've been watching a lot of rap reaction videos as well as following sports news via First Take and Undisupted clips. Listening to a bunch of Cap'n Jazz songs because I just saw them last night. Of these, I'd probably only click on the Fantano video.
What can I say? I love to see old people reacting to memes and dudes dressing up as ballerinas. I like to watch grandmas smoke pot, too. I'm a frivolous viewer. I usually watch with my wife. You should be glad there are no kitten videos.
