I have to load every single page twice to comment or add a video to a playlist. And i've been creating a rather large playlist, and now BAM twice the amount of youtube loading. It's kind of annoying.
Hmm.... that's weird, the same thing's been happening to me for the past week.
I have no idea what's up with that. Maybe your playlist is too awesome for YouTube.
As for me, YouTube won't even play some videos. Those people need to stop sitting on their butts and get to fixing that.
