He's saying two things: 1) I am the only one who knows about this terminology I invented? ("maybe under some other name?", well, how could people know for this name? You invented on your blog, for christ's sake. Obviously you are the first result on Google. Egomaniac.) 2) Then he talks about this abstract Idea, which he thinks is not well known. About the first topic. WTF. About the second topic, not sure if it's such an ignored aspect, but ok, it's a valid point.
