Leadership in a network is not a matter of acquired status or ownership. Those who are able or motivated lead in the areas they are able or motivated in. Natural networkers are coordinators and catalysts who constantly develop matches between people's needs and resources. Different teams will choose different foci of attention. Together they form a structure which could be likened to a hierachy, but which isn't based on authority of command, but on interest.
Groups naturally gather into groups of groups, or sub-divide into smaller groups.
Nowhere do these principles become more pertinent than in the creation of a whole new civilization. You can't create a new cilization by telling everybody what to do. Different people and groups of people have different interests and norms. But by networking freely together and by coming together when we have shared purposes, by taking action when we are able and inspired, and by remaining aware of how our activies relate to other activities, thus we can achieve a synergy, a unity based on diversity.
