I'm doing part 1 at the moment, and the outdated AWS setup instructions on the site frustrated me a bit as well.

Maybe an idea would be to leverage the community a bit more? Make it easier to edit the wiki for MOOC-students which are the ones watching/reading the material later on. And maybe refer to that wiki more on the site.

I end up using the forums a lot for trying to find info on stuff that is not working, or I don't understand. But it's not an easy platform to find information since it isn't structured well.
