MoodThingy is a plugin that any blogger can use to track the emotional feedback of an individual blog post or article. The plugin can be configured to automatically appear below all of your posts, or manually placed anywhere within a post using a handy WordPress tag. A dashboard of MoodThingy stats is also offered so you can see which articles excite, amuse, or bore your readers, sorted by mood or number of votes in the past day, week, or month.

A WordPress Widget is also included in the plug-in as a way to show readers the most popular blog posts in the past day, week, month or year.

You can also find the source code of the plugin on GitHub.

NOTE: If you have made changes to the plug-in code, be sure to make a back-up before upgraded to new versions!
