Recommend

Recommend allows you to add a like user action to your content. Unlike social sharing or commenting, the like action is simple and intuitive.

Stuttter

<p>Use this plugin to monitor the heart-rate of your WordPress installation.</p>
<p>WordPress uses an API called “Heartbeat” to monitor certain conditions and report to the user if something went wrong.</p>
<p>If your login cookie expires while you’re writing a post, for example, Heartbeat will open a modal window and allow you to log in again.</p>
<p>This plugin adds a small menu item to the WordPress toolbar that does the following things:</p>
<ul>
<li>Beats every 1 second to remind you about the API</li>
<li>Throbs every interval of the Heartbeat API to confirm connection is active</li>
</ul>
<p>Future versions of this plugin could add a drop-down to this menu with more information.</p>


WP Heart Throb

Very cool, could be even cooler though with some additional front end features. But I might make a pull request on github.
