Levels of Coordination and Conflict

1. Global level:

• Less direct work (article edits)
• More indirect work (article talk, user, procedure)
• More maintenance work (reverts, vandalism)

2. Article level:

• What does it mean to have conflict at tht article level?
• How would we measure this?

  Language signs of people arguing, disagreeing; Whether conflicts are good depends on the kinds of revisions: proof reading may be good, but if the revisions are reverted back to the original versions, it will be a conflict.

3. User Level

• What does it mean to have conflict between users?
• How can we identify conflict between user?

Many to many communication
