I agree with the article's points that many of today's websites are bloated and user-hostile. A 'spartan' website like that is a refreshing change. I'd add one more virtue to the list: it doesn't deliberately break Reader Mode.

The ideas listed are similar to those of the sadly overlooked IndieWeb community, [0][1] and they complement them. Ideally, the web should be both indie and boring.
