In two full days of effort, I couldn't get a simple set of pages done. I found Play! right after that, and finished the pages completely painlessly in roughly no time.

I would chalk it up to terrible terrible documentation, and being unable to read the example code that I did find due to the Scala practice of using random characters as method names. e.g. something = x % y %% z ||| a

The documentation was really the worst, though. Maybe it's improved in the last year.
