Just a New way to sync your Twitter feed with your Delicious bookmarks. You can do this using packrati.us.
Once you sign up with you Twitter and Delicious accounts, Packrati will follow your Twitter feed, and whenever one of your tweets contains URLs, the site will add them to your Delicious.com bookmarks.
You can also bookmark URLs in @replies to you. In your Delicious account, the service will include any hashtags you include as tags for your bookmark and include the full text of the tweet in the bookmark comments.
