[web2py] Discussion: Why is web2py bad for large deployments?

[Jason Brower]

I love web2py and it's the only framework i feel i am fully capable to do or 
learn to do quickly.
However, I remember see that this framework is intended for small to medium 
sized deployments. Is this true? What is it that stops us from larger 
deployment? Should i pickup django because i may need it?
