What is the difference between Rails and Django in the first 10% of development? I'm pretty into Django right now, but haven't yet given Rails a shot other than reading a short book about it.
Although this has been just my experience, Rails' convention over configuration means that there is minimal configuration needed to get a new app up and running. I have found that Django needs more configuration (then again I'm a Django novice). So perhaps one spends a greater proportion of the first 10% just doing config with Django.
