This looks super interesting. I personally like the way JS is maturing into the back-end, with stuff like this and node picking up steam. What I liked about this site, even while I'm installing it to play with it, is that they seem to have put in a lot of effort on it to make it intuitive + clear , even at such an early stage (just to be clear - this is the first time I've seen it). I'm taking this for a test drive to play around with it, and hopefully if it works well find some place down the line where I can put it to use.
