It depends on the purpose of learning said language. Are you learning to broaden your horizons to explore new paradigms and such? Or are you learning a language because you're part (or planning to be part) of X group who happens to be developing in Y and you just need to be productive/marketable?
I see. There definitely seems to be a connection between coming to Ruby and coming to Python, so this is a fair argument for their association.
I think that them being listed together does however muddle the value of the poll because you cannot tell how many Python and how many Ruby votes there are.
But again, I understand the logic behind their their association as I was someone who was first drawn to Ruby and then later to Python because of its proximity - I have since stuck with Python...
