It is a service that monitors your Twitter account and posts the tweets that contain links to your Delicious account. No need to bookmark them separately. To sync your accounts you need to connect and authorize both your Twitter & Delicious accounts with this service.
It has got some nice options in the preferences section. You can tell it to expand the short URL of link in the tweet while posting it to Delicious. It can also replace your existing bookmarks if any.
