Because you have a fever, and the only prescription is more monad? "Monad" is a loaded term and we didn't feel that talking about them in that way added any value to the book.
I don't know what you imply with fever, I am not a native english speaker, but I just paid for your book. I am also a beginner to functional programming and curious about what monads are and I have read about them without really understanding them.
I was reading up on monads the last two weeks, these are the good sources I have found for Clojure: http://onclojure.com/2009/03/05/a-monad-tutorial-for-clojure... http://intensivesystems.net/tutorials/monads_101.html http://vimeo.com/20717301
