the study of concepts that exist only between people, between people and computers, between computers, between paper and pen, not solely in one place or the other, but linchpins in a scaffold of understanding, keyways of a collaborative driveshaft, keystones in a bending arch permitting infrastructure, that human pyramid we draw upon so often when we believe that anything known can be made use of, when knowledge is spare bricks in the commons, where glowing rectangles convince us any knowledge can be found at no price but time, without changing who we are, with passwords and privacies convincing us that individuals are real and in possession of their faculties, then it happens that all our private keys are public, our concepts revealed shared or rather only real in the sharing, these islands flooding until waves lap the sandy foundations into new dunes.
