Not sure if this in line with HN guidelines (per "tangential annoyances" rule), but god, that "animation: drift 2s ease-in-out infinite alternate;" on body kills me, literally - it redraws the whole page with 120 fps, draining the battery, while nothing changes. I don't think it is even "too common to be interesting" - I rarely see this (or actually, I see such tech for the first time). It is specifically annoying because the article attempts to talk about modern software quality.
