> worse in almost all ways How so? I dislike the text color choice, but other than that it seems perfectly fine to me.
Admittedly most is just personal preference but the line width thing is the cardinal sin. Forcing huge blocks of whitespace on either side of the text for nebulous "readability" reasons is just wasteful. Too many web sites ape this pattern too. Look at John Gruber's website [1] on a nice wide 27" monitor for an extreme example. The content takes up less than 1/5 of the width of the screen. 1: https://daringfireball.n…
Have you seriously tried yourself to read two identical blocks of text, one at full screen width (I tested 100% zoom Wikipedia on a 1440p, 27" screen at standard DPI) and one at a width of about 55 characters on the same screen? Have a go.
I find it easier to locate the next line after finishing one, which gives me a quicker reading speed.
