A production is only as good as it's training and docs.
I would go a step further: 'Training and Docs ARE the Product'.
Having bad docs is like selling a car without wheels -> It's not a car :), rather, not a thing that 'solves the problem of getting people from point A to point B'.
My experience with Scala has generally led me to concur with the overall assessment that Scala information and communication is pretty weak.
Hope they can improve it, it's a pretty cool language.
