Part of the issue is the wide spectrum of code of Haskell that people write. Beginners to Haskell will write code that is very radically different from the code that more experienced programmers write. Not to say that code that one writes in the style of Learn-You-Haskell or Real-World-Haskell level is bad but there is a wide range of choices of how to write Haskell. Haskell also tends to also have a wide gap between beginner material and advanced material and not a whole lot in between. Some beginners will often come and see advanced discussions about the lens library for instance and will assume that they need to learn the lens library in order to program in Haskell. This just leads to disaster since it's nearly impossible for beginners to decipher the type error messages that come out of it until they grok the type system at a more advanced level.
