Heh, the article is kind of negative about Haskell's "success", but fun is exactly the reason why I still prefer Haskell over all other languages.
I'll be blunt about this:
It's probably also the reason statistically no one will be employed to work on a Haskell code base. Same for Lisp, F#, OCaml, etc. They're the hot rods of the software development world where everyone uses SUVs.
Hey, I actually made a point out of laughing about it even as I wrote it - see the footnotes. Haskell's dedication is actually quite remarkable and respectable, and it's not "against success" but against trading "correctness" for "success."
