If it is a journey then where is the beginning? It starts where the sequence scroll, book, ebook/blog leaves off. All of these terms share a common characteristic. They are organized around time. You start reading or viewing at time 1 and finish at time 2. The key understanding to have about maps is that they are organized around space. Time may be an element but space is the foundation.
But why should we care? The answer is that we need to find answers. We need to find answers to the challenges we face as humans on a planet with finite resources, now living in the Anthropocene. We can only do that if we act fast and collectively, across national borders, if we network as people and with our resources. The best way to organize our response is with Cloud-based maps formed around community. All forms of time-dependent activity such newspaper articles, conferences and books, all fall onto a time-line which makes retrieval difficult and choreography of resources difficult. Space-oriented Cloud-based tools allow for movement of resources on the chessboard (which might allow the one idea that works to surface at the right time) and give us an ability to ignore time, so that ongoing, global conversations can be maintained as the time-line threads through them.
DebateGraph in particular gives us an overall perspective of the situation and guides us to the detail we need to understand it. In short, it gives us maps.
