I learnt it quite well actually. Used it in a few projects one quite large. It worked ok for internal apis not open to customers, but even then Django was much better as just setting up the admin side provided a lot of value to the business (for free). All forgotten now but wasted a huge amount of time glueing things together that came for free with Django.
