I'd like to use this to write math textbooks. You start with it fully expanded and as the reader learns definitions and proves theorems it becomes simpler and simpler until eventually it's just a few sentences.
If you still don't understand it, you can expand parts back into more detailed arguments and revisit whatever topic you missed on the first pass.
If students don't understand something, they can manipulate its structure until only the part that the don't understand is exposed and then send a permalink to that view when asking for help.
