Does this have anything to do with Django whatsoever? The title is misleading.
As an aside, I'd argue that any modern web framework with decent community interest also attracts the same "engineering first" individuals.
If you're betting the farm (read: assuming your progressive choice is going to do anything more than speed up dev time) on your choice of web framework you're definitely doing it wrong.
The software you create is a means to an end.
And he implied their product was on mobile devices so may not have involved Django at all.
