Script Summary: Dim out any links on Delicious that you've already saved in your own account. Updated January 8, 2011 to work with new class names in the site html.
This script adds a "dimsavedlinks_post" class to all the post li items that are already saved in your own Delicious account. Then it adds some css that dims out all the posts with that new class. If you have modified the default Delicious CSS in some way (with Stylish, Greasemonkey, etc.), you can change the CSS used by this script to do the dimming so that it fits in better with your custom CSS. Tweak the addGlobalStyle function as desired.
