We've been working on planning the UX for the next generation of MDN.
As my primary mission there, I've been gathering information about the
types of content we have and working with our team (both staff and
volunteer Mozillians) to generate mockups and designs for these content
types.
If you'd like to see the current mockups and ideas, visit:
https://developer.mozilla.org/en-US/docs/Project:MDN/Contributing/Page_types
This stuff is by no means finalized, and the UX team has only just been
shown this stuff to start looking it over, but please feel free to
comment and offer your thoughts.
