Creative Commons licensing is a very cool castle MOAT for WUaS, but where the water is warm, and where anyone is welcome to storm the castle of a free best STEM OpenCourseWare University in all 8k languages, which is actually made of CC sand, which anyone can take, CC "share" and "adapt," and from which they can build their own best STEM school or university castle, in their own language, in any way they want, for example, and wiki-wise too.
Now, because the moat's water is body temperature (like the Harbin Hot Springs' warm pool - https://twitter.com/scottmacleod/status/755078346799591424), people like to float and soak and play in it.
"Are there alligators in it?" someone asked.
Yes, and because they're cold-blooded, they thrive in this warm water - but they're only there once a month for moat-cleaning day (just like at Harbin's once-a-month Alligator day) - and it's the people who don't have access to the warm water in the moat who become the "alligators."
And, you see, this castle is actually a castle-in-the-air, the air of cyberspace, so it's virtual and on the internet - where the grains of sand with which to build are ideas in a sense - so it makes this open teaching and learning wiki sand easier for all of us to create our own schools with.
