I've noticed that on all the videos I've watched, whenever certain users post, they ALWAYS have top comment. As well, almost all of them seem to have the option to reply to their comment turned off, which I find very odd. Does this have to do with the amount of Google+ Followers they have? I notice that a lot of them have lots of followers and lots of people in their circles. I would like to know how to achieve this instead of cheating to top comment by replying to a top comment. Does anyone know anything about this?
