Should ColdFusion developers learn a new language?

Peter and I jump into the middle of the debate started by Neil Middleton with his recent post that directs ColdFusion developers to go out and learn a new language. In the end, the discussion centers around whether there is any particular reason ColdFusion developers should be singled out for this and also whether there is inherently more value in learning new languages as in general skill building. As you might have guessed, I won the debate, though not without going into six overtimes first. You can catch the post on Peter's blog this time around.
