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).

I agree on Real World Haskell. I couldn't put my finger on anything that was 'wrong' or 'bad' about the book, but just got bored with it and stopped reading halfway through.

The Barcode Recognition in Chapter 12 was fairly interesting. Anyone have some good beginning machine vision resources, Haskell or otherwise?

I got caught up a month or two ago in the JSON parser and just kind of dropped it for other projects. It's unfortunate, because I feel like I was learning a lot, but some of the exercises in the chapter can be a bit unclear, and altogether it just wasn't all that terribly interesting.

Richard Bird's book is also really great for the more theoretical side of things (it's like if you took Hutton's last chapter on "Equational Reasoning" and stretched it to an entire book).

I'm working through it now and will be posting notes and solutions as I get them done.

Yep. It's good too. Consider it more of an alternative to Hutton than Real World Haskell.
