> It's also worth considering that the whole paradigm underlying Django and Rails, wherein you render a bunch of HTML with your choice of backend language, may not last forever. With the client side getting heavier over time, the advantages of sharing code across client and server may push the mainstream away from Ruby and Python. Or not. This isn't a prediction; more like a "what if." From that perspective, one thing that Django has going for it is the Django REST Framework (http://django-rest-framework.org/ http://django-rest-framework.org/), which is pretty great. Of course, it's probably the case that Ruby has something similar.
