I also don't like the webpage stylesheet resizing it and ignoring window size; instead it should just use the window size, and the user should change the font, font size, text width, etc, if they want to do so (also, they should implement split-screen).
That is why I use user CSS.
I don't think it is bikeshedding, and I enjoy judging the writer of the blog for their (according to me) failure to understand the common programmer's aesthetic preference for parenthesis-free code and also failing to understand that people mostly have wide-screen displays and full-width lines don't read very well. Are these musings allowed?
PS I used to have some weird fetish for efficiency before I learnt to value readability.
No, but you may get flagged.
