Scuttlepedia
The encyclopedia on Scuttlebutt that replicates and extends #wikipedia
Scuttlepedia-Pub
A pub that follows wikipedia pages. The feed it follows contain the list of patches for the wiki-page of a subject. The pub names the followed pages in its own feed after their subject. A scuttlepedia-pub is called complete if it follows all wikipedia pages. It is called bidirectional if it also publishes changes to wikipedia that appear in the feeds of selected users.
Scuttlepledia-Client
An SSB client optimized for looking up Scuttlepedia Entries by collecting patches about a subject within the existing reach of the user as well as from feeds named after the subject to following the feed made available by a Scuttlepedia-Pub. If there are unresolved conflicts in the history of the page the user is presented with the different versions. The user can resolve such conflicts as well as edit the entry.
A silly idea or something for which there's a long thread from 2017?
Of course, @cel already implemented most of it with ssb-wikimedia.
