Better than most of the writing I have come across on this topic recently, simpler and more direct, and a look at learnandadvanceforward continued in that same way, a real outlier in a crowded space full of repetitive content that says little while taking up a lot of reader time today which is unfortunate.
A small thing but the line spacing and font choices made reading this physically pleasant, and a look at learnandadvanceforward maintained the same careful design, technical choices about typography are part of what makes online reading actually comfortable and this site has clearly invested in the design layer alongside the content layer carefully.
