I know this posting is partly off topic, but I hope it is on-topic enough, and that my partially-novice perspective can be useful.
First, I don't see clone.moodle.org having the same homepage as moodle.org. I'm sure this is intentional for testing purposes, but I think the current homepage has a nice layout, and assuming it works well with smartphones and also screen readers, then I don't see a reason to change it, or at least I think if you do want to change it, you should show it someplace on the clone website, to really be able to fully test the clone website.
But, overall I think the goals of the redesign are very good. What I would really like to see (and maybe it is in some forum or on a page I couldn't find off-hand), is to see how moodle.org works so a school website could make itself the same way. What I mean by this, is that it seems that moodle.org has had to transform Moodle into a fuller content management system, and this is something that I would really love to be able to do for some of the projects I'm working on, as I don't want to learn a whole bunch of different systems, and I'd rather use something that I know will always be in active development, because it is used as the main site for the main project. Plus, if more websites would be more like moodle.org, then there would be more developers, bug finders, etc. to help with moodle.org also.
So in summary, I hope you can point me to a page that gives details about how moodle.org works, if there is a current one. And/Or as the next re-design comes into being, to make a page that gives a fuller explanation of how the moodle.org website works, so that others can take most of the settings, and make their website very similar. (Except for the theme, as I agree that for branding purposes, and lacking confusion, other websites should not LOOK like moodle.org, but having the same functionality would be great!)
