I second this motion. I've been interested in Haskell for some time,
experimented with it several years ago, and then moved on to other
things. That first time around I saw no comprehensible discussions of
monadic IO (for example, I thought that the fact that when you're in a
monad you can't get out was characteristic of monads in general, not a
peculiarity of IO). The state of available knowledge for beginners has
clearly improved since I last looked. I applaud this discussion for
making Haskell more accessible for the newbie.
(Now, if someone would just explain how to get reliable performance
information while jumping through only a bounded number of hoops ... :-)
