We've been using Scala for a while now. It's a major step-up from Java in terms of sheer programming enjoyment (contrary to what the criticism parrots who don't actually use it would have you believe). Java is still very widely used, but most don't use it by choice anymore but rather because it's the default or what the existing code is written in. Go is a non-starter for us due to a lack of support for existing Java libs, and isn't all that interesting compared to the alternatives.
