Structural Holes: The Social Structure of Competition states that networks with "holes" (unbrokered connections) present the most opportunity for potential gains of efficency and strength. These networks (much like the networks of progressive and environmental nonprofits) can be maximized by creation of successful actors with ties to many points in the network.
An interesting side note...Diversity, diffusion and connections outside organizations are the keys to success. In network theory, diversity is not about political correctness it is about growing power for each network particpant. In network advocacy, it is also about the collapse of centralized leadership which has consitently adapted agendas that fractionalize and segment markets (good for corporate PR and sales strategy: bad for political power).
