Can I get any good recommendations for a good Wordpress Thumbs up Thumbs down plugin.

This site is nice the way its set up. But more advanced than I need. They offer this plugin but you use their site and their content. I want my own content on my own site. I want to build my traffic for my site not give it away.

This is a cool concept but I am not to sure of replicating my content to their site seems there could be some issues with SEO etc.

Open for ideas

Thanks
