If you have questions about web2py and want more information about people running it on production, I would suggest you join (even if temporarily) the web2py google group. There are more than 1500 members and a lot of people using it in production who will be happy to share their opinions with you. You will find a very active community. The web2py community is younger therefore not as big as Django's. As an axample, the PyCon 2010 registration site runs web2py in production. It used to run on Django but moved to web2py two years ago. http://us.pycon.org/2010/register
