The idea itself is right. Kudos for that. I could see it in combination with something like redraftable as a powerful mechanism for expression and collaboration.
"Scala works very well with existing Java frameworks. Android is, of course, one big Java framework and we were going to have to interface with it a lot. A number of people asked, given the above, why not use Clojure--this is why."
Since when does Clojure not work well with existing Java frameworks? I wouldn't advocate Clojure or Scala one way or the other since I have little idea of what they're doing, but the above doesn't strike me as sound reasoning.
