Not a word about laziness? This is at this point the most interesting thing about Haskell. As many others have pointed out, the type system has hugely influenced other languages, but laziness by default, for everything, seems like an equally big deal, and equally hard to get one’s head around.
Nope: I think the laziness aspect is very interesting, but it's not something that makes Haskell (for me) a great programming language. Or, at least, it's not in my list of the top reasons (it is in there somewhere).
