Social bookmarking
Social bookmarking allows Internet users to bookmark Web sites and tag them with keywords.
Users sign up at one of many social bookmarking Web sites and are then able to save bookmarks to Web sites in one place, categorizing them using self-submitted keywords or tags.
Users can then share their links with others or browse other users' bookmarked sites to find relevant content.
While you can add a bookmark to your social bookmarking page by simply copying an pasting the URL onto the site, we currently offer instant linking to 
Newsvine, 
del.icio.us, and 
Digg.
You'll find these graphical links in the story tools box inside of each article on our Web site.
