@roder as I stated earlier, I have a wide variety of audience, mainly enterprise devs that are interested also in Scala (which inspires a lot of its feature from both of the language). I guess Joe's statement about having interoperability breaks boundaries (see http://sadekdrobi.com/2009/09/27/a-piece-of-wisdom-by-joe-ar... ) is very important for decision of choice of programming languages. Also the fact that Scala is not a full Actor Model is interesting for audience of InfoQ. The User's Model is very important regarding programming language design since once you get to performance issues you need to look beyond this model to actual implenmentation (I guess you are aware of tutorials that oversemplify concepts like Monads and Lazyness to mention few). I am glad you found an interest in the interview, and thank you for your constructive critics.
