One of the great things about Twitter is the wealth of useful links that get shared between users. My conservative estimate is that 25% of the resources that I've bookmarked over the last few years have come from Twitter users. The one thing that I wish Twitter had was an option for bookmarking those links without having to open them outside of Twitter. Packrati.us was built to do just that, bookmark links without leaving Twitter.
To get started using Packrati.us authorize the service to access your Twitter account and your Delicious account. Once you've authorized Packrati.us it bookmarks in Delicious all of the links you Tweet or reTweet. If you're a frequent user of services like Four Square or Gowalla you can tell Packrati.us to ignore links from those sources. Packrati.us also allows you to specify hashtags to ignore or to add to your links.
