I've just watched the first 3 sessions of Beyond Belief 2006 (http://beyondbelief2006.org/Watch/). And I really love the way they discuss! It's not only very interesting and funny, it's the first time I've watched discussions on such a high level! Not ONCE have I noticed how one of them disrupted the argumentation of another (other than reminding them not to drift too far away from the topic) even when they do not agree with the other party. They patiently wait till the other person finishs and then adresses the issues about which they are concerned. They open mindedly listen to each other and you somehow get the feeling that it is constructive. That everyone there learns something from each other. I think this should be a good example for all of us in real life.
