A new tool offered by Digg--the new shortURL and toolbar service (also called Diggbar) has substantially increased its web traffic by essentially keeping web users within the Digg website as users view and interact with external web pages. You may also see this service being increasingly used on Twitter as well--as users continually try to find more inventive ways to keep their "tweets" under 140 characters (URLs included). All a Twitter user would need to do add "https://digg.com/ " and their old address becomes a new digg tiny url.
