I tried (and still working) with both languages that power the respective frameworks, and from my own opinion they are the same. I've been in your situation too and the best way to find what framework suits you is to go and try them, build something.
I wont respond to your question as I've a little more inclination to Ruby/Rails than Pyhton and I don't want to influence your decision, you should really try them both and find by yourself.
That was fast, glad you interviewed my "proposal". Amazing how much you can learn from a woman regarding management, they think in such way that no man can do.
I don't have an iPhone (waiting for 4 ;/) and so I cannot give a proper review. But as a first impression I think there's to much clutter, you should think at a better category organization, like putting "Top 10 a..z" in their own category as now important category are sinked and there's way to much to scroll, even on a PC.
Also try a more subtle item gradient, it's too "eye catchy", just try to whiten more that grey (maybe make it fully white).
And the site speed looks a little bit slower but this just might on my end so no real problems there.
