I use the heck out of the admin. I wouldn't say I'm super experienced with Django, but my solution to users being overwhelmed by doing things there is to build a bit of extra UI just for the stuff they need to do, more Rails style. Meaning: I don't go into fighting too much with the admin when what it can do out of the box is not feasible for some. But even if the admin ends up being used only by devs and some trained folks, I think it has amazing utility.
