We've been planning a re-design for this site (moodle.org) for some time (MDLSITE-1862) to make it more useful, more international and easier to navigate. Moodle.org is based on our own Moodle platform plus a custom theme and custom plugins and scripts for our special needs.
The pieces (and time) are finally starting to come together now so I hope we'll be able to launch the new-look site later this month.
If you want to discuss any of the proposed changes, there is a discussion in the Moodle Community Sites forum.
