Static Web Content is simply a content item which is not part of a Section or a Category. Static Web Content cannot be added to a Blog, a Section or a Category. Static Web Content is, in other words, an independent, stand alone page. Static Content pages can be created, edited and deleted in the Static Content Manager. In the sample content you have installed with CMS, the Main Menu choice “The Mambo License” shows an example of a Static Content page.
Web content is dominated by the “page” concept, its beginnings in an academic settings, and in a setting dominated by type-written pages, the idea of the web was to link directly from one academic paper to another academic paper. This was a completely revolutionary idea in the late 1980s and early 1990s when the best a link could be made was to cite a reference in the midst of a type written paper and name that reference either at the bottom of the page or on the last page of the academic paper.
When it was possible for any person to write and own a Mosaic page, the concept of a “home page” blurred the idea of a page. It was possible for anyone to own a “Web page” or a “home page” which in many cases the website contained many physical pages in spite of being called “a page”. People often cited their “home page” to provide credentials, links to anything that a person supported, or any other individual content a person wanted to publish.
Blogs are a type of website that contain mainly web pages authored in html (although the blogger may be totally unaware that the web pages are composed using html due to the blogging tool that may be in use). Millions of people use blogs online; a blog is now the new “home page”, that is, a place where a persona can reveal personal information, and/or build a concept as to who this persona is. Even though a blog may be written for other purposes, such as promoting a business, the core of a blog is the fact that it is written by a “person” and that person reveals information from her/his perspective.
