I just requested a refund for MEAP for "Secrets of the JavaScript Ninja", that I ordered almost three years ago. I didn't expect it to take that long...
At the risk of sounding like a broken record on this topic, I will state again that "Joy of Clojure" is a very good book. (I'm a Clojure newbie, so I can't judge its technical content, just that it is well written.) The Manning early-access program is highly disappointing. We got an update in August 2010, and then again on March 18, 2011. Nothing in between.
When I pre-order from PragProg they update their PDFs much more often, and I can see the evolution of the book.
I just downloaded the finished ebook. Searching for "monad" returns three hits. :lemonad, one mention to monadic and one mention of monads in the source list. I was a little disappointed.
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.
