Wordpress
Categorize and Tag Your Posts
WordPress.com includes an easy system which allows you to categorize and tag your posts while you write
them. We automatically create archives based on your categories and add
them to our global tag system and our tag surfer, so you get extra
traffic as other people interested in the same topics as you will find your post and leave comments on your blog.
