Interesting Talk: "Django's architecture - the good, the bad, and the ugly"

I've just watched this interesting talk about Django's architecture by Andrew Godwin:

• Django's architecture - the good, the bad, and the ugly

Andrew Godwin is a Django core developer and the creator of the great South, "a Django application to provide schema and data migrations".
In this talk, he gives a good overview of Django's architecture and his opinion about which are the good, bad and ugly parts of Django.
