I am not trying to start a flame war, these are just comments from my experience of trying to get beyond text-book examples and start using Haskell libraries and trying to learn from open source code. In general I find idiomatic Haskell hard to understand, and for me this is a barrier to using Haskell for real projects. Maybe someday I'll have learnt enough to get past this problem, but as the language and libraries seem to evolve quickly, I have my doubts...
