The author is the CEO of a company that sells the first (and only?) commercial Haskell IDE. I point this out because the author (from his background) clearly knows about the subject matter, while reading the content of the article would lead you to believe the author was a novice to software development and computer science. The shallowness of the article combined with the background of the author can be reconciled if you understand the article as an advertisement.
