This seems like a forced false dichotomy (perhaps for rhetorical purposes, but then it isn't as important as it claims to be). What I mean is that I somewhat doubt most people fall into either of these two camps. I would bet most work linearly, keeping in mind vague parts and ideas for elsewhere - maybe keeping notes in AN extra document, but also not limiting themselves to working strictly forwards. Until there is a medium of non-linear consumption, I am skeptical of the need for serious tooling around non-linear documents besides what we already have (mind maps, graphs, etc - all things with products for them but ultimately the biggest thing keeping this from translating well to the computer is the mouse and keyboard, not the software)
