Wikipedia:Article content

An article on Wikipedia should contain content which causes that article to actually cover the stated topic of that article. The title of an article is an important ingredient, albeit an obvious one, in accurately delineating the topic, scope, and focus of that article.

Perhaps it is germane to note that in logic, the law of identity states that each thing is identical with itself. (It is the first of the historical three laws of thought, along with the law of noncontradiction, and the law of excluded middle.)

Description
An article's topical focus and scope can be deduced from the title of the article. The content of the article can be greatly broadened, revised or altered, as long as it is germane and beneficial to maintaining the scope and content of the article, so that the article actually covers the stated topic of that article.

Examples

 * History of United States government. A topic that is self-evident in its notability; however, someone had to make a decision about the best way to actually approach this topic, and then someone had to actually write it. so this is one good example of the importance of the seemingly obvious fact that articles need to have content.
