And cross-posting G+ comments makes YouTube comments worse not better because many times when people share video on G+ the text is just the video title or something like: Must watch video title or "Checkout this video on YouTube". Showing these in the YouTube comments is useless spam. Also there is lot of "empty" comments with only a "shared this via Google+" thing which is even more useless. It's turning into something like the end of Tumblr posts with page long list of likes without any comment.
