What's the next step to learning Haskell after monads?

I've been gradually learning Haskell, and even feel like I've got a hang of monads. However, there's still a lot of more exotic stuff that I barely understand, like Arrows, Applicative, etc. Although I'm picking up bits and pieces from Haskell code I've seen, it would be good to find a tutorial that really explains them wholly. (There seem to be dozens of tutorials on monads.. but everything seems to finish straight after that!)
