A few things I can’t stand about Youtube’s desktop website:

1) Spacebar sometimes skips to the next video when playing a playlist. Just why?

2) You never know if the small buttons like play next on the thumbnails will work or just play that video right away.

2) when on the homepage, you open a few videos in new tabs and close the homepage only to find out that you just open bunch of “this video contains paid promotion” disclaimer pages. Re-open the homepage to actually open the videos and they are all gone, the page shows a grid of different videos.

so yes, I agree that the web interface went downhill.
