This new "federated" wiki model innovates three ways.
a) It shares through federation,
b) it composes by refactoring and
c) it wraps data with visualization.
The "story" is a collection of paragraphs and paragraph like items. The "journal" collects story edits. Should you take my page and edit it as yours, I can see what you've done and may decide to take your edits as my own.
