So in their attempt to make people use Google +, G is rolling out a YouTube comments change. You can only comment using your Google Plus account (and name). YouTube comments will now be automatically filtered to give priority to: Video Uploader People in your Google + circles "Popular Personalities" aka YouTube celebrities, users with lots of views/likes/comments You also have the option of sharing your comment to google + (I think they are desperate for content). To view all comments, you will have to click, wait for it, "All Comments". Why are they doing it? Google say it's to cut down on comment spam and trolling. Why are they really doing it? To make people use Google + socially and punish facebook. So what does this mean for us blackhat comment gamers? To really dominate YouTube, we need lots of Google + accounts, with wide circles, AND popular YouTube videos. Once you've built up some strong accounts, your comments will get filtered to the top WITHOUT upvoting, making it even easier to drive traffic.
