This addon adds buttons below your posts (or somewhere else) to make it easy to get reactions to the post, but without the hassle of writing a whole comment. It makes it easier for the reader to interact with you. The buttons are configurable (how many, what text, position) and simply are counters to how often they were clicked. There is also a widget and a shortcode to show the top x posts with the most clicks for each button.
The idea is inspired by a <a href="http://bloggerindraft.blogspot.com/2008/08/new-feature-reactions.html" rel="nofollow ugc">blogger feature</a> and since it’s been my first addon, I borrowed the structure from <a href="https://wordpress.org/extend/plugins/sociable/" rel="ugc">sociable</a>.
<h3>Restrictions</h3>
<ul>
<li>When using plugins to cache the pages, the buttons won’t be up to date. They will increment through the javascript, but when the page reloads the old count will show again, until the cache is deleted. Check the FAQ on possibilities how to change that.</li>
</ul>
