Google officially ends forced Google+ integration on YouTube

Google said it will no longer require Google+ accounts to use any of its products, and it will continue to strip Google+ integration out of all of its products. The YouTube blog announced that "in the coming weeks," comments will no longer require Google+; as of today, comments made on YouTube won't show up on Google+, and vice-versa.
