“[N]ew technology enables new kinds of group-forming.”

“Tools that provide simple ways of creating groups lead to new groups, [...] and not just more groups but more kinds of groups.”

“Unlike sharing, where the group is mainly an aggregate of participants, cooperating creates group identity.”

“[B]ecause the minimum costs of being an organization in the first place are relatively high, certain activities may have some value but not enough to make them worth pursuing in any organized way. New social tools are altering this equation by lowering the costs of coordinating group action.”

“Communications tools don't get socially interesting until they get technologically boring.”

“The centrality of group effort to human life means that anything that changes the way groups function will have profound ramifications for everything from commerce and government to media and religion.”

“Society is not just the product of its individual members; it is also the product of its constituent groups.”
