The DiggBar is a URL shortening service that puts your website within a frame on digg.com. As a result, the user sees Digg’s URL, rather than your URL in their address bar, no matter which page they navigate to on your site. You can see an example DiggBar URL that points to google.com: <a href="http://digg.com/http://google.com" rel="nofollow ugc">http://digg.com/http://google.com</a> which is automatically converted to <a href="http://digg.com/d1nYVs" rel="nofollow ugc">http://digg.com/d1nYVs</a>.
The No DiggBar WordPress plugin automatically redirects anyone using the DiggBar service, so that your site’s URL is displayed in the address bar of the browser.

No DiggBar

This plugin redirects DiggBar users to your actual site.

WP Digg This is a plugin that adds a Digg button, but with a twist. Instead of adding a Digg button to all your posts, WP Digg This plugin selectively adds the button only to posts you want.
To add a digg button just add a ‘digg’ custom field with value ‘1’.
WP Digg This can display digg button on your single pages but there is an option to show them on home and archive pages as well.
