The Management of Categories

Open-site stores information using a system based on categories. Therefore, the way in which categories are maintained has a great overall impact on the rest of the project.

Empty categories don't help anybody. It is okay to create several empty categories, if you plan to put some content there in the near future. However, empty categories don't help the surfer and in general should be avoided.

Use category sections whenever possible in order to split up large amount of information located in the same page. For example, if you have a category dedicated to the economy of a country, and you include information about agriculture, industry and tourism, keep at the top of the page an overview of the economy, and create 3 category sections dedicated to the fields specified above.

Also, it's suitable to create subcategories when you have enough content in the parent category and you want to split it up. It's suitable to find a balance between crowded pages and empty subcategories.
