My main app of choice is YouTube and it's just astonishing how much amazing educational content there is on the app.
MIT OpenCourseware, 3Blue1Brown, PBS Eons, SmarterEveryDay, ... and I could go on and on....
DESPITE THIS, their recommendations and the YouTube search has gotten so unbelievably terrible over the past few years that it's just becoming unusable.
Their recommendations have nothing to do with the channels I'm subscribed to, instead it's so much goddamn crap with click-bait titles/thumbnails (because one of the biggest factors for the YouTube Rec. Algorithm is thumbnail click-through-rate).
For YouTube search, if you search for "schlieffen plan", then sure the first 3-4 recommendations will be based on what you searched. BUT after that, the fucking recommendations have nothing to do with your search query... instead it'll just be completely random stuff that the YouTube algorithm thinks you might click on.
It's gotten completely unusable with YouTube shorts now because they're trying to shove that shit down the throat of their users (99% of the YouTube shorts are complete fucking garbage).
It's really a shame because there's so much amazing content that's been uploaded to the YouTube platform, but the idiots in charge of the company are completely ruining the app... especially over the past few years.
