notes an Industry Standard feature on Deletionpedia
— a collection of 63,559 deleted Wikipedia pages that range from "vanity entries" or obscure points of reference to heavily edited topics that Wikipedia editors eventually deemed fan fiction
, inadequately sourced, or otherwise lacking. Looking through the collection of removed articles, it's apparent that entertaining minutiae are often the target of Wikipedia editors: "Geek lore seems to be a particular target for deletion, with the deleted page of the month a comprehensive guide to 'Weapons of the Imperium (Warhammer 40,000)'. Deletionpedia provides links back to the Wikipedia deletion discussions, which are a lesson in magnification of minutiae; the Warhammer page was removed due to philosophical disagreements over what can be considered credible source material, while a page listing every chalkboard gag in The Simpsons opening credits spent 691 days on the site before being deleted as 'fancruft.'"
Note that while Deletionpedia uses MediaWiki, it doesn't have wiki functionality — readers can't alter or update archived entries.
