The contrast between this Nielsen-Norman (NN) page and the OP page is marked. The NN page is much easier to absorb the information. More succinct, way better page layout.

Both articles have information/direction worth heeding, but there is irony in the fact that the OP page adopts same-text size and paragraphing conventions of yesteryear that the NN page does away with.

It's also frustrating that Hacker News doesn't pay attention to some of the information. In creating an edit to an existing post, the feedback after clicking on the 'update' button is not as clear as it should be. (It's a screen redraw, I guess).
