We just came across Packrati.us, a simple bookmarking service that allows you to essentially sync your Twitter feed with your Delicious bookmarks. 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. Here’s an example of the White House Twitter account’s tweeted URLs in Delicious, using Packrati’s tool.
Last summer, Delicious launched a deeper integration with Twitter, to allow you to also tweet your bookmarked links out. Packrati’s ability to add the URLs your Tweet out to your Delicious bookmarks is so simple, yet serves as an incredibly useful tool to store and organize the links you send out. Of course, you may not want to bookmark all of the URLs you Tweet out, so the site could make your Delicious account a bit noisy.
