From the Wikipedia page for the User:Diikiw/Wiikid:
User:Diikiw/Wiikid, formerly Wikiid, is an article that was created on the web site Wikipedia in 2008. It is notable in its attempt to become the first Wikipedia page to gain notoriety solely for the fact that it was a page on Wikipedia; this was intended to spark a debate as to whether or not Wikipedia could be considered a source notable enough to allow a page’s permanent entry on the site. It can be looked at both as metahumor and as a piece of postmodern art.
The article argues it is notable — and, therefore, ineligible for deletion — because “it marked the first time that an article on Wikipedia managed to create original content while at the same time following Wikipedia’s requirements that every article must be factual and cite its sources.”
Wikiid’s creator also made a defense as to the article’s artistic merit: it was the only piece of work ever created that managed to be perfectly compliant in every way to Wikipedia’s requirements, while simultaneously being a commentary on the nature of Wikipedia (and, therefore, on the nature of user-generated content online). Its creator stated that its many joking citations to itself, rather than being sloppy editorial work, were attempts to make Wikiid as involved a piece of work as possible, using all of Wikipedia’s various features to create an original piece of work.
