between like-minded groups/individuals who communicate w/each other about their efforts. you know, like on Twitter and Facebook.

maybe i'm in Portland and i see on Twitter that like-minded ppl in Spokane have done __ in their work on a cause that concerns us. i see that and decide that i or my group in Portland can do the same or something similar. so i reach out on Facebook to the Spokane group for feedback and tips. they share info and i share it w/my ppl in Portland. and we take action.

or someone tweets that at high noon on a certain date we should all do __ in a joint effort to accomplish ___. other ppl agree and/or propose __. like-minded ppl who are interested in the cause join the discussion. plans are made in various locations. boom. it's done.

no single leader involved though. and a 'network' exists.
