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.

I'm simply generalising here.

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. ;-)

Svbtle looks like the most straightforward blogging platform since Posterous v1.

Well, he certainly excited interest in it.
