I see a ton of people have been using the free code I submitted on hackernews and one person using a Twitter code since yesterday even opted to buy a copy! Hey awesome, thanks!

It would be really great to get people's feedback, but you don't have to comment here - I realize it may take some time to digest since it's 200+ pages. Remember if you subscribe you can just send me an email at any point if you come across an error or something that wasn't quite clear, or just any other idea of how I could improve.

thanks!
