In other words, I think it would be so highly useful to have a browseable corpus of arguments and conclusions, where people could collaborate on them and perhaps disagree with portions of the argument graph, adding to it and enriching it over time, so other people could read and perhaps adopt the same reasoning.
I play around with ideas with this site I occasionally work on, http://concludia.org/ - really more an excuse at this point to mess around with the concept and also get better at Akka (Pekko) programming. At some point I'll add user accounts and editable arguments and make it a real website.
I thought of it while daydreaming about how to converge public opinion in a nation with major political polarization. It'd be a sort of structured public debate forum and people could better see exactly where in the hierarchy they disagreed and, perhaps more importantly, how much they in fact agreed upon.
