This is pretty amazing!!!
If I had to choose between the two color sets, I like the second one better. (I think that is the only difference….)
Can’t wait to test this out!!!
I don’t think it is incorporated/coded yet–still in Alpha, so I guess we just have to wait.
Looks great. However, for the Demo page, I would add a page with an overview of the demo (instead of linking to it). Say something about what version it is (or if it is updated on nightly builds, whatever) and give a few points of what to check out. When I registered, I had an idea of what I wanted to look at, but it would be cool to see what you want us to look at. Make it a show off page.
Sweet. I love having one login for everything. Makes life bliss, no?
No gravatars, though. 
Soon, I hope.
