The idea behind collective work is that we're all attempting to perform individual tasks, and the ways in which we accomplish our objectives interact. Sometimes this is because we're all part of a larger project, and sometimes it's just because what we do can affect other people's plans if they know about what we've done. Sometimes, what we're attempting to do generates conflict with other people's objectives, and other times it generates opportunities. It would be great if we knew of these conflicts and opportunities - and if the Internet could tell us.
