Rails certainly has a larger community than Django's, but I have found the signal to noise ratio is higher on the Rails communities as well. All that attention has come at a cost. There is also Python vs Ruby documentation and library support to consider, of which Python arguably wins, though Ruby is catching up. All that said both are a excellent option and IMO roughly equivalent.
