LOL don't you love the new Google+ layout for Youtube they make you jump through a hoops and set up a COMPLETELY DIFFERENT inbox feature which sends you notifications instead of review comments?
I also loved there update 6 months ago "You can no longer sign in with a user name, only emails" ... 2010 Youtube >>>>>> Present day Youtube.
Also why is google trying to compete with Facebook?? They decided to integrate everyone's Youtube channels with Google+ so people are forced to sign up using their horribly confusing interface just to access things they could access before.
