I didn't like it. Too much visual overhead. I didn't know where to look. Also a few things went wrong (don't know what). I was clicking around in code window when the tutorial guide on the left disappeared, then I tried refreshing and everything went blank. So I clicked on url in the navbar and pressed enter. Now the page loaded. But everything was blank inside the boxes. OSX 10.8.3 with chrome. Ohh, I found out what went wrong. I tried scrolling in the code window and the browser went back to the last page which it thinks is: http://learn.knockoutjs.com/ http://learn.knockoutjs.com/ and that makes the tutorial disappear.
