Delicious can be used to provide a dynamically-updated feed of relevant news vetted by a trusted network of journalists.
Josh Korr recently wrote about starting a group on Publish2, where journalists could share links to news items about the current financial crisis. Commenters from FT Alphaville, Seeking Alpha, and DNC Bloggers used various technologies to accomplish similar results.
A Delicious-powered model would require very little technical resource.
The “social bookmarking” service makes it easy to create a personal network of trusted aggregators. Bookmarks from that network can easily be filtered to show only pages tagged with a particular phrase, like … “linking.”
Plug the feed into your site for your readers get a constantly-updated list of news from different sources, vetted by experienced journalists, or other trusted experts.
