is the 29th anniversary of the launch of the first wiki! On March 25, 1995, [[Ward Cunningham]] launched the [[Portland Pattern Repository]], which is still available today at http://wiki.c2.com/
Since then, countless other wikis have been born exploring everything from patterns & [[pattern languages]] to organizations, to [[fandoms]], to [[journalistic efforts]], to individual projects, to entire [[movements]], and beyond, including of course many of the world's largest [[encyclopedias]]. Countless people use wikis every day, because wikis have become a key part of how humans tell – and edit – our [[stories]].
