The Randomizer WordPress Plugin
The Randomizer is a WordPress Plugin that allows an administrator to automatically include a fresh, randomly generated selection of posts to their blog footer on each and every page visit. The randomizer makes for a nice addition to any WordPress site, considering that search engines love to see dynamically changing content. Once the plugin is activated, random posts from your site are automatically loaded into the footer since the footer section is generally considered non obtrusive to the visitor.
