I have been reading old pragpub magazines on my Nook. After reading through the "Thinking Functionally with Haskell" articles I thought I would give it a little whirl. I don't think I am going to invest too much time into it to be honest as I would prefer to invest my time in improving my FSharpishness; but a little peek never hurt anyone eh?
The articles start in August 2012 http://pragprog.com/magazines/2012-08 and carry on for a couple of months.
I have found a good tutorial from the main Haskell site too http://learnyouahaskell.com/chapters
I haven't really had a proper look yet but will do as soon as I get a little time :-)
