A nice and super simple way of adding ratings in your posts.

This plugin adds the ‘Like’ button and ‘Who Likes’ list to:
<ul>
<li>WordPress posts and comments</li>
<li>BuddyPress activities and comments</li>
<li>BBPress posts</li>
</ul>
It allows for registered users to like the items. And it shows for both registered and unregistered users the existing likes.
The components to show the likes to can be configured on the settings page. For example, the likes can be disabled for WordPress comments.
Likes are saved in the internal WordPress and BuddyPress meta tables. No separate tables are created.
The plugin cleans all its data on uninstallation (but not on deactivation).
