I'm not asking for some major, crazy redesign. 16px is the browser default and most websites aren't using tiny, small font sizes like 12px any longer.

The only reason HN is using it is because `pg` made it that in 2006, at a time when it was normal and made sense.

Maybe the issue is not scaling according to DPI?

OTOH, people with 30+ inch screens probably sit a bit further away to be able to see everything without moving their head so it makes sense that even sites which take DPI into account use larger fonts because it's not really about how large something is physically on the screen but about the angular size relative to the eye.
