I've been searching for this comment. This is the first time I've heard of this phenomenon and I'd consider myself a heavy and long time user of YouTube

YouTube always amazes me that there can be content creator with millions of subscribers (or number of uploads in this case) that I have never heard of.

I hit his videos a couple of time, it was on really niche technical subjects for witch I would not expect a Youtube video to exist. If someone would have made one, it would be better ranked. But sometimes Youtube impress me with videos on some really niche subjects, which is amazing, but when you click on one of his videos, it's really deceiving.
