Twitter uses Scala heavily. It is one of my favorite languages. I love Scala, but it's also sprawling and complex, and requires great care to code for readability without getting too cute. I would expect there is a lot of code at Twitter written by Scala show-offs and acrobats that the remaining engineers are going to have to read and understand now. Ooofff.
