<p>This plugins display a highly customizable list of random posts. There are some plugins that serve a similar purpose already, with one drawback: If they’re used along with cache plugins (like WP-Super Cache), the list is cached also, and remains the same over thousands of views, thus not so “random.” AJAX Random Posts, as its name says, uses AJAX to retrieve the posts and overcome the problem: now each page refresh comes with a different list!</p>
<h3>Features</h3>
<ul>
<li>Compatible with caching plugins, since the core is written and run in JavaScript which is normally not cached.</li>
