This new WordPress Plugin, Kudos, brings a new unobtrusive alternative to Facebook’s like button to your WordPress blog. Kudos, as seen on the svbtle.com blogging network, are an unobtrusive and playful way for your readers to show their appreciation. To give kudos for a post the visitor simply hovers the Kudo-Button: A small animation starts for as long as the visitor does leave his cursor on the Kudo. When the animation is finished and the Kudo-Button is filled the count goes up by one. By clicking the then filled button the visitor can take his Kudo off the post again.
You can see the plugin in action on the top left of this post. Dustin Curtis, creator of svbtle.com and inventor of Kudos, describes Kudos like this:
Each post has one unusual feedback mechanism which has no external repercussions: Kudos

Beside the default automatic insert into your posts you can make use of the PHP-Functions and shortcode to display the Kudos more individually. Take a look into the description on the plugin repository for more information.
Future updates are planned to bring more customizability: Different speeds and images, more positions in your blog etc.
