From the article:

Functor and Monad are hardly underrepresented.

The exact wording was, "What <features> do you feel are under represented or often misunderstood?"

I agree that Functor and Monad are hardly candidates to dominate that survey, the burrito notwithstanding.

Maybe I misunderstood the topic as the poll itself isn't linked on the blog, but I got the idea that this is a poll on "what topics would you most like to learn more about?" and I would guess that most Haskell programmers are very comfortable with Functor, Foldable and Monad already.
