I don't imagine the average consumer would ever notice but I wonder how much it is used by youtubers to arrange collaboration between different channels in similar spaces. At least as a way of establishing initial contact. It would be a shame to see collaboration between channels drop as that, in my opinion, is one of the best parts of the medium.
