I like the layout, the 3 tabbed areas are intuitive. Is it aimed at complete beginners? The tasks were easy but the videos made them sound hard or described actions using vague terms. After completing a chapter I didn't feel rewarded just a little confused. The feeling of progress & logic is a key essence of learning to code. What you explain in the videos doesn't quite link with the task so I think for a total novice it would be confusing. Just a few points compared to other in-browser coding tuts that I've tried in the past. I found the video tough to see what you were typing even with the vid at full screen. The text on the sketches was also a little small. Success message should be clearer. I only could tell I had got a chapter right by the green tick, the 'success' message was " Your app should respond to web requests. Display "awesome" somewhere on the page" - (even though I had written "My awesome URL shortener") I was left feeling as though I had missed something. The errors it throws up when you get things wrong don't point the user in the right direction. e.g "RSpec::Expectations::ExpectationNotMetError: expected #has_selector?("title") to return true, got false" The clicking/highlighting of text on your example pages during the video gets really distracting, especially for users who will watch the videos several times over. I think if you refine the videos a little more it will become a great resource. Even if they become a little scripted it becomes more formal structured learning and less friend to friend chatter. I'll keep checking back to see what other stuff you add!
