This post didn't strike me as a ton of anything. It was pretty succinct. I agree with stormbrew above that the value here is in stating clearly what the purpose of a monad is as a way to lead in to a better understanding of a monad. With knowledge of what a monad is, many people will probably stop reading there because they're not interested in getting close to pure functional programming.

Yeah, I tried to be clear that "I’m not going to explain monads."
