You accused the comment of being a trolling comment when it was pretty tame, maybe not entirely serious, and thus we had the bubble comment as I usually find people so oversensitive kind of need that.
I had seen the ask me anything stuff some time back and also saw some people defer to it instead of having a proboards forum or something if they decided youtube comments were not where it was at. Had a quick look and it did not seem to be the sole residence of (m)any experts that made it their internet home like has happened to a lot of computer stuff with spiceworks. With all that I thought it was just another simple service that can be ignored like most of them (granted I will ignore everything given half the chance -- wait long enough and everything is a fad), and for the most part still do. I find it useful enough if I am finding info on people I guess but about the same as any forum really.
I guess I would be inclined to humour someone a bit more than I was when I was told I was crazy for not being on myspace or then facebook, but not by a lot.
