I bought this a few months ago, and it was very well done. The videos were informative, and the overwhelming majority of the exercises were useful and clearly written. Almost all the bugs have been worked out by now. The interactive console is is a fantastic way to learn with immediate feedback, and this implementation is better than any of the others I have seen.

I will say though, that after basically paying to beta test it, it does pinch a bit to see that it's free now. Oh well. I really hope these guys succeed, because they are doing great stuff.

Stoked to try it out! Thanks for making it free Gregg.

Awesome, I will start this tonight!

Yae!
