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.
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.
I am tired of only ever being gauged by immediate usefulness. You hiring?
Also when you emphasize "exactly", you are not giving any actual reasons.
