I'd say mind-maps meet flow-charts meet wikis. What looks very nice as a way to organize knowledge and discussion. But that would require some really well designed navigation, for example: - where(in the graph) am I located right now? - what will happen if I click this box? - what should I do do get to X etc. Hope you are already thinking about it :) Also, I'd like to ask about all these labels on the arrows (indeed, answer, about, example, precision etc.). Are they meant to be used in some automatic processing of the data? That would be really neat. Good luck!
