agree.. I really like scala and Li's blog and book have helped me immensely. I use it mostly for spark, but I've found it really useful now for other things.

The concurrency really is pretty nice (compared to other languages). His API's are written in the same way as his blog and his book: zero condescension; he's not constantly trying to impress you. This seems to be the problem with the language.. the language allows you to really go nuts if you want to and the result can be an incomprehensible type system that takes a week of hacking just to figure out what it wants you to do. That said, json4s isn't terrible.
