"DebateGraph is an award-winning, cloud-based service that offers individuals and communities a powerful way to learn about and deliberate and decide on complex issues.


It does so by enabling communities of any size to externalize, visualize, question, and evaluate all of the considerations that any member thinks may be relevant to the topic at hand – and by facilitating intelligent, constructive dialogue within the community around those issues.


Moreover, each public map contributes to, and forms part of an accumulating graph of structured understanding across a growing range of topics, which, as the topics intersect, accelerates and enriches each community's understanding of the topics each is addressing." -- from source: http://debategraph.org/
