wikidoc:What is an article?

A Wikidoc article is defined as a page that has encyclopedic or medical reference-like information on it(i.e. containing differential diagnoses, imaging etc.).

An "article" does not include any pages in any of the specified namespaces that are used for particular purposes, such as:
 * the WikiDoc namespace for material about meta subjects related to Wikidoc(example, Policies & Guidelines and its talk page);
 * the talk namespaces for discussing what the content of pages should be (for example, Talk:Abdominal Pain)
 * the special namespace, whose pages are created by the software on demand (see Special:Special pages);
 * the user namespace for pages that are used by individual Wikidoc writers (example, User:CMichaelGibson).
 * the image namespace which is used for describing and attributing images (example, Image:Anatomy.jpg)
 * the MediaWiki namespace which is used to define shortcuts and other text strings used around Wikidoc (example MediaWiki:Disclaimers)

But not all pages in the article namespace are considered to be articles; the most notable exceptions are:
 * the Main Page;
 * articles which contain no internal links;
 * thousands of disambiguation pages which are used to resolve naming conflicts;
 * thousands of "redirect" pages which are used to re-route one page to another page;
