Sticky posts are a feature added in version 2.7 of WordPress and can be used for a variety of purposes. The most frequent use is to mark posts that should be "featured" for an extended period of time. These posts often contain important information or highlight things (like a product announcement) that the blog author wants to display in a prominent position for a long period of time.
First, place your cursor inside of a Loop where you're displaying posts and want to single out your sticky content. Inside The Loop, after a call to the_post, insert the following code:
<?php
if(is_sticky()) {
?>
<div class="sticky-announcer">
<p>This post is sticky.</p>
</div>
<?php
}
?>
Create a sticky post on your test blog and take a look at your site's front page. You should see text appended to the sticky post, and the post should be moved to the top of The Loop. You can see this in the following screenshot:
