I just found out about BuddyPress (a collection of plugins that convert a WordPress MU install into a social network) and now I was wondering if there are any Digg-like voting plugins for WordPress. This would eventually integrate into a BuddyPress website, where the site members would submit, vote and comment on stories (much like Digg).

I have a feeling I will end up having to build this from scratch, but since the site will be built on WordPress, I was wondering if there were any plugins already available that add this functionality. So far I have come up empty in my search. I did find a Wordpress blog that had this functionality WpVote. It even creates thumbnails of the story webpage automatically (I'm assuming) using websnapr. I browsed through the page source and didn't seem to find any hints of a WP plugin that they are using.
