Very simplistic framework with minimal footprint and loads of flexibility. Not constrained in architecture, design and interoperability at all. Had no concerns with the learning curve as well, as had not even heard about it when I got to work on a product already developed in Web2py.

MVC model helps tu build up applications faster

This is a wonderful framework, which makes web development really fun for a newbe. I would recommend all newbies to learn this framework as it will be mainstream in the future. For web2py long term backward compatibility is a primary goal, together with security. The web2py community is open and friendly and it gives concrete support to newbies and old timers.
