As all of you may know, Google has now integrated Google+ into Youtube, forcing users to use Google+ to post comments and edit their Youtube account. Google's move to force Plus onto YouTube has outraged the YouTube community and more.
I hate to put a dampener on things, especially as the new G+ comments allows malware and such - but they aren't going to change it. It's too much time and money to have a separate accounts team and such for YouTube, when all other Google owned products are linked under the same account.
It'll die down soon, just like all the other updates they do.
