The team I am on at Time Warn Cable has been doing Scala for almost a year now. 5 of us flew out to San Francisco to attend Stairway to Scala training.
The training was great, I really enjoyed the style of having 2 instructors. One of them doing traditional lessons and the other one would work on the REPL. To engineers things are more real when you can see running code. It's obvious that Dick and Bill put lots of effort into the curriculum.
I recommend the training. Dick Wall and Bill Venners are awesome instructors. The Time Warner Cable crew was pretty punchy and the instructors managed to keep their cool.
