Just my 2 cents:
I think it's best to keep the old design, but pimp it a bit.
To start off with the layout:
-With a nicer shadow under the header, a few darker grey borders and
an addition of a text-shadow on the menu anchors, then it's a much
better website already.
Then for the content:
- Maybe a homepage-showcase / tutorialcase (done with a php-curl to
David Walsh's latest mootools blog) will keep new and oldschool
mootools developers interested.
- Comments both in the Forge and the Docs that can be clicked open to
discuss what's going on with a Doc-example or Forge-plugin.
- people should somehow jsfiddle things to explain examples and
bugs / questions
- Then on the homepage: Latest 5 comments on the Blog / Docs / Forge.
This will get peoples attention to what's going.

I'm looking forward to it all :-)
