Interesting, I really disagree. I do agree the page is refreshing compared to a lot of the internet these days, just because it has no ads and no glitchy, laggy SPA animations or slow loading times.

But it's pretty extreme to pretend that none of basic design practices adopted over the past 30 years have any merit whatsoever. This design is not good. The black text on white is too much contrast. The default browser text of Times New Roman is less readable than more modern sans serif fonts (this is arguably a problem with Chrome's default value though, not just this site). The graph titles are not text but rendered into the images, and the images have no alt text to help with accessibility. The double solid border on cell boundaries in the tables looks crazy and does distract from the content. The page content is much narrower than it should be on desktop, it could use an adaptive width. There is no dark mode to make the page easier on your eyes in low light.

The design here on HN is a much better example to strive for, it has a similar minimalist aesthetic but addresses most of these issues.

I wish more of the internet behaved like this, but I do not need it to look like this.
