On WeWrite App, a Group should be allowed to easily split off into other communities, with minimal friction or drama. This idea comes from the Origins of WeWrite.
The pages should be easily copied and taken in a different direction, since many of them have shared foundational texts, but have different interpretations.
Here's an example of how this kind of thing has worked in the past: You'll notice it's very evolutionary, when contradictions arise that are so great they create a split where the communities pursue their own independent aims.
This idea comes from WeWrite's origin story, where the founder experienced such a split but it was on MediaWiki software, so it was a hard break and a messy process, instead of being a natural and organic process, which is how the history of ideas actually progresses.
Hopefully this can allow for many thousands of schools of thought to emerge and compete with one another in a healthy and rational way.
Here's a dynamic graph view showing the evolution of a GitHub repository over time using a software called Gource. Not only could similar visualizations be used to show communities and how they split over time, but it could also be used to show the version history of a page over time.
