Correct. But if the page is, at least in part, an art piece rather than an information dump, or needs to do interactive rendering for its purpose (an editor like the markdown example, live updating status displays, games and other interactive toys, etc), then the tech is necessary and this article is useful.

Which is something like less than one percent of websites, and this technology is deployed much, much more widely.

		Again, correct. But “don't do this if you don't really need to do this” is rather pointless to say, hence is being downvoted, because people already being that sensible don't need to hear it, and those who are not are unlikely to listen. The comment is just noise, as unnecessary as the unnecessary animation and other gumf that it is railing against.
