DebateGraph is a tool for visualizing and sharing thought networks. One way to think of it is as a collaborative thought processor. 
In contrast to a word-processor's closed documents, this thought processor produces open-ended, easily-linked, cloud-based "maps."
 
DG encourages iterative improvement. It has wide application. More than ever, we need thoughtful, idea-driven tools for collaboration.
