I like LYAH as a reference and cheat-sheet but I found it a little slow for learning Haskell.

Here's my recommended order for just learning Haskell:

http://yannesposito.com/Scratch/en/blog/Haskell-the-Hard-Way/ 80% completion here is fine if you feel your attention waning, the next thing will address hammering in things like functors and monads via typeclasses.

https://github.com/NICTA/course/ this will hammer in the lessons in a very direct form by forcing you to confront the challenges and lessons learned by the creators and community of Haskell itself. Doing the exercises here is critical for being fluent.

Real World Haskell is available online. I recommend it as a reference only.
