Learn ROR or Django and make some traction. If you ever want to manage start ups you should have an idea of what's under the hood.
How should someone choose between the two when the priorities are time and quality of the learning resources online? Rails has RailsforZombies and the Poignant guide. Does Django compete? Which would be more valuable on a resume?
I like Django documentation, I'm a rookie and I'm making progress. Progress is encouraging.
Start with Zed's LearnPythonTheHardWay... then move onto Django.
Rails will get you there, too. My support group is familiar with Django, which is generally the biggest deciding factor.
Soo, I'm going Django and not looking back.
