Fascinating article, wwh. Thanks very much for posting the link.

I especially enjoyed reading the arguments about discussions that should be aborted and those that should be tended carefully with attention taken into which hands the precious ideas should be given. Some audiences would misuse precious information. So, it becomes a point of responsibility to the 'facilitator' (term in the article) to choose the parties in dialogue and to help worthy participants to bring forth their best ideas.
