The term Word in WordPress refers to the words used to compose posts. Posts are the principal element (or content) of a blog. The posts are the writings, compositions, discussions, discourses, musings, and, yes, the rantings of the blog’s owner and guest authors. Posts, in most cases, are the reason a blog exists; without posts, there is no blog!
To facilitate the post writing process, WordPress provides a full featured authoring tool with modules that can be moved, via drag-and-drop, to fit the needs of all authors. The Dashboard QuickPress module makes it easy to quickly write and publish a post. There’s no excuse for not writing.
