Having finally finished my first read of LYAH (It took me months of reading, practicing and taking breaks to let it all sink in), I can only see one way to improve upon it: Make a video series.

I don't know enough about Haskell to pull it off (though I may try if no one's done it in a year or so). However if someone could inject the wacky sensibility* of things like LYAH, Computerphile and CodeSchool.com into a Haskell video tutorial, it would do worlds of good for the community. Better yet, if someone could make an interactive class like CodeSchool or Codecademy, that would be amazing.

* Thought I should mention that the wackiness isn't the only important part, it also needs to be properly paced. That was LYAH's other strong point, they hammer home each concept with multiple examples before moving on.
