I have used web2py for the last few years and have been happy with it: - well designed components: DAL, SQLFORM, views, etc - commitment to backwards compatibility - works on GAE - helpful community (groups.google.com/group/web2py) - thorough documentation (web2py.com/book) The main criticism of web2py is that its design is not 'pythonic', which is irrelevant to me.
