actually I checked before posting and it seemed that no one had ever posted this on HN or reddit.

It might be old but it's not outdated. I have discovered it a few days ago because I'm doing something with CSS grids at the moment and I'm checking this page everyday.

EDIT: ok the warning at the top "CSS Grid Layout is currently supported by very few browsers" is outdated but the actual cheatsheet is definitely not :)

There's a difference between outdated and un-updated.
