ASIDE: I've been using learn you a haskell for great good! http://learnyouahaskell.com/, and found it helpful, insightful and the examples nicely paced so you can treat them as exercises as you go.... up until the module chapter, which is more like a reference, very long, detailed, tedious. I got up to here
http://learnyouahaskell.com/modules#data-char (check out how small the scroll bar slider is on the right - this is a big chapter).
Did this stop you or how did get past it?
How does Learn Haskell Fast and Hard compare?
