YouTube's Help channel shared this video to give a simple overview of their new comments system connected to Google+.
The big overhaul is that comments are sorted by people you know, popular conversations and better conversations. You can also privatise comments so only you and your Google+ friends can see them, otherwise they show up to everyone on YouTube much like the old system.
For instance, as I shared this video on my Google+ profile earlier, my comment (mentioning more of the new features) has shown up under the video along with the source and any replies.
As you can see from the likes/dislikes on the video, a great deal more users don't seem to like the feature than those of us who do! Comments on the video are also the usual expressive variety (with many also working out that hashtags are a feature in YouTube comments), but I'll leave you to look at those yourself.
So what do you think? Is this an improvement to YouTube and an incentive to be more active on Google+? Or is it as many are commenting to be a terrible idea?
