We are not used to writing with a view to perspective. It is unusual to write about a topic or process from more than two perspectives - for and against. These are not rich perspectives.
Writing with strangers is a phrase we use in wiki. It captures the central importance of the relationship between individual authorship and perspective creation in wiki. Every time someone forks a page, we create a new perspective on the same topic.
Federated wiki is designed to proliferate perspectives and the experience of this new form of writing can be intoxicating.
