MDN already has compatibility tables for lots of things; if they're missing from a particular article, it's not because they're unsupported, it's because nobody has done the research and filled in the information (it's a wiki! You can add things!).
MDN didn't do a good job of advertising itself as a wiki. It wasn't until recently that you could login with a GitHub account.
When you google "can i use flexbox", caniuse.com comes up but MDN does not.
The other thing missing from MDN, is that caniuse.com shows browser support as a percentage. Now I know I'm safe to use flexbox since its supported by 97.74% of browsers in the wild.
When a new feature comes out, I add it to both MDN and caniuse. It would be great if these two could be integrated as well.
I don't like that caniuse by default shows only several recent browser versions, deceiving developers and making it look like some new technology is supported everywhere. It is clearly a "dark" UI pattern that motivates developers to make sites viewable only on latest Macbook.
Instead, it should show the year since which some feature is supported.
I actually like how it currently works because it doesn’t matter if Chrome 32 didn’t support feature X because no one is using it. The boxes are sized by their current usage and aligned based on the stable version.
It’s a perfect chart to show your boss when someone complains about Firefox 4 not working. Clearly that person missed a few updates :)
That being said, I would like a year on each column for the occurrences when time/year is relevant. Currently I just Show All.
