#Wiki was invented by Ward Cunningham in 1995, to support the Portland Pattern Repository http://c2.com/ppr/ .

#FederatedWiki was invented by Ward in 2011, enabling parallel editing in a community. Renaming a "wiki page"​ as a "card"​ may make it more intelligible to novices (even those who don't remember #hypercard).

Restarted #federatedwiki for sharing #patternlanguage .
