Stumble! for WordPress extends WordPress to support a “random article” feature, similar to <a href="http://www.stumbleupon.com/stumblethru.php" rel="nofollow ugc">StumbleUpon’s StumbleThru</a> and Wikipedia’s (Mediawiki’s) random article feature.
It has shown that it can significantly increase pageviews on a blog.
The plugin supports basic “go to any random page” functionality, but can also integrate with <a href="http://mitcho.com/code/yarpp/" rel="nofollow ugc">Yet Another Related Posts Plugin</a> to stumble similar articles. Stumble! for WordPress will automatically (optional) give priority to articles with more comments, so users will be brought to your most popular posts.
Since version 0.2, the plugin also shows statistics to show total number of stumbles, and hits to individual articles as a result of Stumble! for WordPress.
New for version 1.0: You can now enter the Stumble! for WordPress network (from the options panel) which will send your traffic from stumbles from other blogs! (and visa-versa)

A simple WordPress admin tool for inspecting rewrite rules. View a listing of all your rewrite rules, see which rewrite rules match a given URL (and the priorities they match in), or filter by different sources of rewrite rules. Perform a soft flush of your rewrite rules to regenerate them.
<a href="https://github.com/Automattic/Rewrite-Rules-Inspector/" rel="nofollow ugc">Developed on GitHub</a> — pull requests are always welcome. Please leave feedback, questions, bug reports, and feature requests in the GitHub issues.
<h3>Where to find it</h3>
Go to <code>Tools → Rewrite Rules</code> in the WordPress admin.
<h3>URL Tester</h3>
Quickly test any URL (or path) against your site’s rewrite rules:
<ul>
<li>See whether the URL would be a 404 or which rule would match first (the one WordPress uses).</li>
<li>View the list of all matching rules, in match priority order.</li>
<li>Inspect the query variables extracted from the match and the resulting final query WordPress would run.</li>
</ul>
Works with full URLs or paths and automatically handles sites installed in a subdirectory.
<h3>Permastructs</h3>
Browse a table of all permastructs that WordPress is aware of, including:
<ul>
<li>Name — the permastruct key (e.g. for posts, taxonomies, authors).</li>
<li>Structure — the permalink structure pattern used to generate rules.</li>
<li>Description — a human-friendly summary of what the permastruct controls.</li>
</ul>
