The power of K2 is in the idea of categorizing your data, thus making it easier to manage. This will be especially helpful as your site grows in content. Many sites are fully article-based and it is not uncommon to see a site with thousands of articles on it.

The first recipe will take into account a site that has been in operation for a while and has K2 added to it.
