When I look at this screenshot [1], it seems to suffer the same issue as LWN: After around 100 characters the text should begin on a new line, not after it filled the screen. One can complain about lots of rules designers use, but this one is actually scientifically backed up. I wonder why so many websites still do this wrong, maybe web developer tools in browsers should throw warnings?
