Haskell has plenty of legitimate criticisms for use as a production language. However this article isn't it. Please don't read this and repeat the opinions posted here. A lot of what the author says is just plain wrong and shows a misunderstanding of basic functional idioms. For example: "Functors are basically an Object with a internal state changing method in typical OOP terms." Uh, no. Functors are stateless, with a well defined semantic. This is nothing like an object with internal mutable state, with instance methods that mutate it in god-knows-what-way. There are a lot of mischaracterizations like this in the article.
