Awesome! This is one of the most comprehensive tutorials I've ever seen. It still never fails to amaze me what FOSS contributors offer to the public domain. So I ask, how long did you work on preparing this and what percentage was content oriented and what percentage was presentation oriented.

Thanks very much. I worked on it on pretty steadily for about a year and a half. Most of the work was figuring out what I thought would be the right order to present things and how to explain the concepts. The content itself I was already mostly familiar with, though Haskell was pretty new to me.
