Before you go any further, you should know these things: 1. Deployment and scaling is a lot easier on Rails b/c of several dedicated hosting providers that specialize in Rails. Engine Yard is the one we use, it makes scaling extremely easy. I'm not sure if Django has similar companies. 2. Rails-specific SAAS are super awesome. Newrelic/Hoptoad, etc. They make tracking your software and errors a lot easier than the less supported Django. 3. Speed is a non-issue; scaling is 100% about making the DB scale. Furthermore Ruby 1.9 is going to be faster than Python 2. 4. Training a developer to learn Django is not as trivial as you think. There are a lot of "tricks" in these frameworks that make working in them very fast, these take time and experience to pick up.
