Learn You a Haskell for Great Good (http://learnyouahaskell.com/) is another good resource for learning the language. It's a bit lighter weight than Real World Haskell, and doesn't have the breadth of practical examples, but I think it makes up for that by being more consistently interesting. I went through LYAH first and then Real World Haskell, and although the latter was very informative and useful, I found it to be painfully dull in certain parts (particularly the chapters that discuss the building of a JSON parser).
