With Movabletype and many other platforms categories enable a wonderful way of organizing your blog. Each post in this blog is allocated to a category (or more than one) which means readers only interested in one topic (for example) can easily find every article on the site focusing upon it. In effect you can end up with many targeted mini blogs within the bounds of your full blog with categories.
