The Kodex Posts likes plugin allows your visitors and logged in users to like or dislike your posts, pages, and custom post types. 
The AJaX based interface is clean and fully customizable. 
The Dislike button is not required, and the buttons labels are editables. 
The buttons shows their counter. 
Shortcodes are availables for display the buttons on your post content and for the Like counter only. 
In the admin interface, columns are showing the actual count, and there is a metabox in the editon page.

Kodex Posts likes

A simple interface for including like/dislike buttons on posts. Keep up the good work! 
In future I'd love to see a dashboard area where you get a quick snapshot each posts likes / dislikes which you could sort, search and filter to make it easier to review the feedback, but it's not essential.



Really Great Plugin

It does exactly what I need. It is very simple and works well. Seems to be a clean install and lightweight functionality.  Hopefully the author comes back to do an update soon. Many thanks for this wonderful plug in.

This plug in is simple and great. Out dated but it still works.

This plugin provides one upvote( like ) and one downvote( dislike ) button with counter, to each of your posts. The site admin has option to set the position ( before or after a post ) and orientation( left or right ) of these buttons.
The site admin has the option to set the voting mode per post. Each post can either be “restricted”, i.e. is votable by only a logged in registered user, or, “open”, i.e. any visitor can cast her vote for the post. For the posts in “open” mode, the site admin can set a time interval for a user to cast consecutive votes for a particular post. The logged in user can optionally be allowed to cast multiple votes for a single post, or, to vote a post only once. If she is allowed ( by the option set by the site admin ) to cast multiple votes for a particular post, she is prevented for the pre-set time interval to cast a consecutive vote.
The admin interface has a complete list of all the posts that have been voted so far and she can reset the counters for either a particular post or multiple posts at a time.
Other settings provide options to specify the number of posts to display per listing page, etc.
If you find this plugin helpful, PLEASE RATE IT!!
