Another point about Roland's experiment that I just blogged.
What he asked people to do was to say who it would be really useful for them to meet in the near future. Whoever, wherever it was, and regardless of the perceived likelihood of getting what they want. This gave the experiment a bit of an edge, and I sensed a bit of dramatic tension, because he was, in effect, asking people to reveal themselves, and to be vulnerable.
That's another thing that conventional meetings are terrible at doing; they assume we all know what the audience wants, which is to hear the deep wisdom of the wise speaker. The deeper truth, which this experiment points to, is that we're all rich and complex folks with all sorts of unmet needs and desires - and in these lies the real potential for connection.
