I'm an old-fashioned Java developer - I still haven't got around to using any of the scripting languages on the VM. It's definitely time that I got around to it, and right now Scala seems like the most appealing choice. According to Martin Odersky, of Scala/Typesafe fame:
Java 7 will mean better runtime performance for Scala developers. In the future, invokedynamic, a new Java bytecode, will also gain importance for developers.
So it seems that we're definitely in the age of dynamic languages on the VM - so which language is the most popular within the JavaLobby community? Please choose the one that you use from the choices below. If you're like me, and haven't used any yet, just indicate which one you'd be most likely to use.
