It's not just the search deteriorating. The frontend is littered with bugs. If you write a comment and try to highlight and delete part of that comment, it'll often delete the part you didn't highlight. So apparently they implemented their own textfield for some reason and also fucked it up. It's been like that for years.

The youtube shorts thing is buggy as shit, it'll just stop working a lot of the time, just won't load a video. Some times you have to go back and forth a few times to get it to load. It'll often desync the comments from the video, so you're seeing comments from a different video. Some times the sound from one short plays over the visuals of another.

It only checks for notifications when you open the website from a new tab, so if you want to see if you have any notifications you have to open youtube in a new tab. Refreshing doesn't work.

Seems like all the competent developers have left.
