The replies are true, but to your question, yes. Right now would be a good time provided you were on square footing with both.

Rails the framework I think is better than Django. I just found conceptually it had more of what I wanted already in there. However coming from a Java/Perl background, Python was easier for me to grasp and read over Ruby. And timing wise, I wouldn't deploy or upgrade a Rails app until I felt comfortable with the security issues being addressed. Hell, I wouldn't want to surf the internet with an app running on my computer today.
