As a "sort of" haskell programmer recently I admit I found it quite funny.

If only because you could fit all of the Haskell programmers into a barrel of standard size? I think that's the point of the article, actually.

More because it's easy to poke fun at Haskell in this way, even the Haskell people know they come off as obtuse and academic. AFAIK there's been much soul-searching in their community about how to get past that.

While Steve Yegge is a good satirist, I see this post as an extended version of this joke from the "Mostly Wrong History of Programming Languages":

Haskell gets some resistance due to the complexity of using monads to control side effects. Wadler tries to appease critics by explaining that "a monad is a monoid in the category of endofunctors, what's the problem?"

I love that joke, because I barely understand it, but minimal understanding just makes it funnier.
