Why? The font size is 1em – whatever you picked as your default font size, respecting your wishes. The line length is set in a way that it fits about 100 or so characters. That’s in my opinion a few too many (I would go for 60 to 70) but it’s certainly a very reasonable number. You should also note that the line length can be reduced by making your window narrower. Line height is at 130%. That’s miles ahead of the awfully cramped default (look at this comment to see the awful default in action). I would add quite a bit more – mostly for aesthetic reasons – but 130% is, once again, a very reasonable number. The text provides a summary and has an ample amount of subheadings. Paragraphs are used to give the text room to breathe. I’m not a huge fan of the aesthetics (I would go for a serif font – not because it’s more readable, it’s not, but because it’s prettier – and I would decrease the line length and increase the line height) but I can’t find any faults with the text’s readability.
