WordPess comes with a default category for blog posts called: Uncategorized! (Wow, how original.) WordPress automatically assigns a post to Uncategorized if you fail to specify a category.
But I caution against this since a Category search is an important tool for your visitors. Think of a Category as an organizing tool to lead your visitors where you want them to go to find more information. Proper use of categories allows visitors to focus on a specific area of interest, easily locate related material and gather more information, in this case about YOU!
Your Web site and blog are filled with information, almost like a filing cabinet. Think of categories as a file drawer with a lot of folders (tags, in a discussion I will write later) in them. Or folders within the file drawer with relevant information within the folder. Or a library sections such as fiction, non-fiction, reference, etc. Use categories to help lead your visitors to the right folder, article or aisle on your Web site to make his or her journey easier. Thus careful thought is required in setting up categories.
First, let me show you how to change the default category.

Click on “edit” and the following screen appears:
The screen below shows I changed the “Uncategorized” to “WordPress Resume site” by typing over Uncategorized. I also added “General tips and hints about using WordPress.com as a resume or portfolio site” in the description. Some Themes display the descriptions when you mouse over the Category name, other Themes do not.
You can continue adding new categories under “Add New Category”. As with Pages, you can also make children or sub-categories of a Parent Category. You can also add categories on the fly as you write and publish a post as shown in the video on the Posts page.
Most themes display that post’s Category immediately following the post with a link to other articles you place in the same Category.
You can also display your categories as a custom menu in a secondary navigation bar or by adding the Category “Widget” to any widgetized area.
There are two schools of thought as to whether you should limit one category to each Post or assign several categories to a post. My feeling is you should limit each Post to one Category. Then you can add several “Tags” (or keywords) as sub-organizing topics. I talk about “Tags” as being folders within the filing cabinet drawer, or articles within a folder or the Dewey decimal system used to organize books within a library’s sections.
The Tags page has links to WordPress support information and instructional videos as well.
