The image that tries to illustrate how frames per seconds affects motion is wrong. At least in my browser, it is crossfading between images in the 30 and 15Hz illustrations. That's not how video works: you show individual images sequentially with no mixing. Simplistic attempts to "improve" motion are universally worse than leaving it alone.

Most display technologies essentially crossfade between sequential frames due to the response time of the image display elements. There's been a lot of work on reducing this but it's still a thing.

This is great article but the contrast on the body text is horrible on the eyes (ironically)

It's 92% contrast, and passes Web Content Accessibility Guidelines at the highest AAA standard for contrast. What more do you want?

Not OP, but at default zoom level, the text is too thin - most of the pixels aren't actually black - they are subpixels smeared across two columns.

100% contrast. People went to great effort to achieve the highest possible contrast in print, e.g. with barium sulfate coated paper, optical brighteners in paper, single-use carbon film typewriter ribbons, oil based inks so pigments could be used instead of dyes, etc. Contrast is good. The only good reason I can think of to use less than 100% is for syntax highlighting.
