Great slides. As a relatively new and inexperience Django user, the points I found most troubling are the points on Apps, and the points on the Auth model.
I also think that getting started with Django is harder than it could be. There are a lot of things you're forced to do, and decisions you're forced to make about how to structure your code, that should be made for you. For example, reading thedjangobook, several times the authors tell you "you can put that code in this file, or in this other file, or maybe do it like this". As a new user, you want there to be a consensus on code structure, and for that consensus to be forced on you: one less thing to worry about.
One point I would like to mention: I haven't taken part in the Django community at all, but if jacobian's comments to this thread are any indication, it looks like it's a great community. Seems to be a really helpful and open person.
It really is a great community. The django-user mailing list and #django on freenode are very newbie-friendly. I would recommend lurking on both and picking up a lot of best practices by osmosis, then asking questions when you get in a bind.
