I'm not sure how much generalizing you are doing. But, I was quite literally inspired by the exact words Dustin wrote: "essence of blogging" as well as the recent unveiling of his UI. I don't think I ever claimed he coined anything.
True, but in essence you're saying that you're amazed that everyone doesn't know everything. No one knows everything, and few people have encyclopedic knowledge of a niche topic like blogging. I'm amazed you didn't know that. ;-)
