Well, I guess I wont be watching any videos from my subscribers for a while.
I'm subscribed to about 100 different people, many of whom upload up to 6-8 videos per day.
The old layout (and the one before that, to a lesser extent) nicely sorted the videos by channel and let me x off ones I'd seen or didn't want to watch. Now, I have to scroll through 2.5 pages of Lets Plays to find the one video I actually want to watch at the moment, and quite frankly I'm not going to put up with that.
To top it all off, I cant X off the Lets Plays and other videos I don't want to watch right away, meaning if I want to watch 3 videos way down the list I have to scroll down every goddang time.
I honestly don't expect to be using Youtube for a while after this, because all this update did was make it a whole lot less simple to find my videos.
TL;DR
Google is fucking retarded and whoever thought of this needs to be shot 50 times in the dick, then fucked with a rake.
I hope some group like Anonymous runs their company into the fucking ground for this load of shit.
