Huh, I had the opposite reaction. I thought that it was a very nice, clear article, which is phrased to be approachable by as many people as possible with some amount of technical background. That technical background may not be as programmers. It may be power users, or web developers, or the like. And I thought the analogies and illustrations helped out with giving some context that people who aren't systems developers might be missing.
