I think it says a lot more about the fact that learning (and, therefore, the best text for learning) is highly subjective than it does about the worth of Haskell.

I mean, how does the logic even work that leads from "some people think that this text is good for learning about X but I find it is 'inadequate and sometimes confusing' to me" to "X isn't generally worthwhile" even work?
