Seems apropos in light of many discussions here. This group (paraphrased and don't hold me to the details) has a published list of rules requiring civil discourse and, apparently, people abide by it. People post a position they hold and, by rule, have to support it and respond to people making the counterpoint. I heard that some threads are 80 pages long (ain't nobody got time for that). Interesting experiment.
