“Our social tools are not an improvement to modern society, they are a challenge to it.”

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

“[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.”

“One of the biggest changes in our society is the shift from prevention to reaction...”

“[T]he ways in which the information we give off about our selves, in photos and e-mails and MySpace pages and all the rest of it, has dramatically increased our social visibility and made it easier for us to find each other but also to be scrutinized in public.”

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

“The basic capabilities of tools like Flickr reverse the old order of group activity, transforming 'gather, then share' into 'share, then gather'.”
