When you think about it, the hacker group Anonymous is probably one of the world's most do-ocratic organizations. Regardless of where you stand on Anonymous' tactics, politics, or whatever, I think the group has something to teach developers and development organizations.
As leader of an open source project, I can revoke committer access for anyone who misbehaves, but membership in Anonymous is a free-for-all. Sure, doing something in Anonymous' name that even a minority of "members" dislike would probably be a tactical mistake, but Anonymous has no trademark protection under the law; the organization simply has an overall vision and flavor.
Its members carry out acts based on that mission. And it has enjoyed a great deal of success -- in part due to the lack of central control.
