I've been creating personal demo sites, but it's far too early. The code is still very broken, and you can't even get past the installation without needing to make changes. I don't mean this to be insulting, it's just that parts are being overhauled, which means the code right now looks like a building in the middle of renovation. It's interesting to look at, but you don't want to work there until the work's done.

It's best to wait.
