Django CMS is very good and pretty popular. I've used it on 5 decent sized projects now and my clients love it's in-page editing. The dev community is active and the next version looks really promising.

Publicity stunt by Microsoft?

According to the whois[1], yes.

The contact email @microsoft.com at the bottom of the page didn't make it obvious to you?

You know that old TV show set in an office, where all the female staff took a break to drink Diet Coke and ogle at the window cleaner? Turns out it was just a publicity stunt by Coca Cola.

No shit!

Looks very similar to https://gomockingbird.com/ which has been around for a while.

Mockingbird looked great, but it hasn't been updated since 2010 as far as I'm aware.

Sounds similar too. There's no easy way to pan in both.
