This new layout is horrible. I'm only subscribed to 30 pages but it still a tower because of IGN and Machinima videos being posted every day. I have to actually scroll down much more than the old format even when I didn't check Youtube out for days. Everything feels clunky and way to complicated.
The ONLY ups I give to this new format is making all the uploaded videos viewable instead of the latest ones. That and improving the close thumbnail "x" working better. After that, this new layout sucks. It's not like the new channel formats where at first you don't like it because it's different or because it makes your old layout useless but your don't mind it anymore.
Why would you change something that was working just find. No one complained that the old format was bad ever. You know why? Because we were happy with it!
