Django is a weird case too because the official docs are so good and also offer very good tutorials. And the Two Scoops book is such an invaluable reference too. Reading both would put you in the position where you won't really need SO for Django questions.
Definitely, the official docs are fantastic. A lot of the SO use came from having a solution based on the docs, but wanting to check I wasn't missing a prefered/recommended way to do it, or being fairly sure something would be a Django built-in but not finding it (so SO was a bridge from how I was describing something to where it was in the official docs).
