Delicious is a Social Bookmarking service, which means you can save all your bookmarks online, share them with other people, and see what other people are bookmarking. It also means that we can show you popular bookmarks being saved right now across many areas of interest. In addition, our search and tagging tools help you keep track of your entire bookmark collection and find tasty new bookmarks from people like you.
