Federated wiki creates new sites on first reference. We've found this to be liberating in that each site provides a unique vocabulary for the writing that takes place there.
We fork pages that have utility in multiple contexts. This frees each site to be as independent and connected as convenient. We've adopted an abrupt, to the point, easily refactored writing style that regains context by surrounding pages.
Emergent site structures tend to be topical, chronological or reflective. Pages are written quickly and then updated occasionally. A page copied to a new environment will be adjusted to fit.
We designed for desktop authoring while viewing three to five wiki pages at once, tablet reading while viewing two or three page and smartphone reference retrieval showing only one or two. We have not yet shown this to be the prefered use of touch devices.
Our design favors non-conversational collaborations suitable for more thoughtful writing. Authors are not guaranteed to know what has become of their words.
Random identifiers are created for each paragraph. These survive through editing and copying. Pages sharing a paragraph of common origin remain implicitly and bi-directionally linking by id. Search engines then become the external link-store that makes bi-directional links possible.
