Slightly off-topic, but a personal pet peeve of mine is `<meta name="viewport" content="user-scalable=no" />`. My vision isn't as great as it used to be and not being able to zoom is awful. I usually just keep my browser around 80% the size of my screen and zoom the text on a per-site basis for comfort, although I can see this varying a lot based on a person's exact setup (screen size, distance, etc). Apparently I browse HN at 210% zoom.
