There's a limit to how much I want to try to read up behind a tutorial when I'm just trying a new framework out. If my natural desire to understand what magic lines of code does causes me to break focus, tab out, google a bit, find some explanation that may or may not even be correct... yeah, I get put off a little.
And yet the argument here in favour of Django is that not as much is hidden from the user... which may cause some users to lose focus as you put it.
I find this this statement hypocritical.
This basically just says Rails has a better user interface than Django (not necessarily something I agree with).
Django makes you feel like a power user because it forces you to learn more in order to use it?
