Digg
From Pvmwiki
Digg isn't just a plugin, or modification to your wordpress setup, it's a website. The concept is that people put the "digg" buttons on their site, and if someone likes what you did, they can "digg" you. The diggs are gathered on the digg.com webpage and the effect it has is that your blog posts find another area to be published, but also for readers to generate more traffic for you by "digging" your articles.
