Inclusionism
Inclusionism is an opinion about the quantity and range of material to be included in the online encyclopedia Wikipedia (and, by extension, other online encyclopedia projects like the Citizendium). The key argument inclusionists make is that, unlike a traditional encyclopedia, online wiki encyclopedias can be significantly larger in size. On Wikipedia, notability is the requirement that articles are held to. Deletionists claim that articles about subjects which are not that notable should be deleted, while inclusionists argue for the inclusion of articles which, though may not seem useful on the face of it, are still part of the "sum of human knowledge", what Wikipedia aims for.
Larry Sanger, the founder and current Editor-in-Chief of the Citizendium, is an inclusionist. The Citizendium operates under a more inclusionist policy of Maintainability rather than notability.
