Very nice. Really well made. Love the fact that I could just dive in and engage with the product from the homepage without having to dance through the usual annoying sign up routine. One thing I'd change is this error message which is not really an error message : "ERROR: Sorry, that's not correct. Please try again." It appears every time I try some command which is not exactly the next step defined in the tutorial. It kind of feels like an old school tutor forcing me to follow a rigid book exercise and discouraging experimenting. If you want me to complete the tutorial, don't move the progress indicator until I complete the next step, but please don't scold me with fake errors :-) One thing I've been craving for is a place where I can jump in and get a quick primer on some random topic from another programmer. Think SO in real-time. I know there's IRC, but it's not very user friendly and I don't want to hop around different channels to ask different language questions. If you build a truly social and interactive site for learning programming, I'd use it a lot. Good luck!
