The title of her post at Naked Capitalism says it all. But the rest of the post is well worth reading, too. Yves shares her own experience with this process.
What I would add is this is not new. It is the way the countercultural movement was organized in the Sixties, and it is derived from ancient tribal cultures worldwide.
It is also how all the organizations in which I have participated since then have been organized. It's cumbersome at first, but it works by building consensus, mutual appreciation and trust, clarity, and coordination. It is based on interpersonal group dynamics and increasing adaptability rate by freeing exploring options.
Those who participate in this movement are going to learn a lot that will stand them in good stead for the rest of their lives. It sure changed my life. I got involved in this after coming out of the military, which is about the most top-down, hierarchical, and authoritarian organization in existence. What a contrast.
It is also how things work in the blogosphere through the interactivity of comments. It's one reason I am here. It works.
