What kind of Plugin is the New Playstation Share Blog using | Wordpress

Love this feature http://share.blog.us.playstation.com/ Users are able to post requested features and then vote them up or down. Is this a plug-in that can be downloaded?

Thanks, Tim

Well if you took 5 seconds to look at the source (all resources from wp plugins are served out of thier respective directory) you would see this is indeed a plugin. It is called wp-postratings

edit: Byron Whitlock points out which plugin they're using. Looks like they did a lot of customising, though.

You might consider saving yourself the implementation work and just using Google Moderator...

It is using the wp-postratings plugin, however, I will say that it isn't extremely modified. The only thing we changed was fixing some bugs with binary (up/down) voting. Everything else is handled via added rewrite rules and wp_query filters.
