The Original Social Bookmarking Site Delicious is the original social bookmarking site that allows users to save, organize, and share bookmarks through tagging. It has unique social features like sending bookmarks to others and following users with similar interests. Users bookmark websites to organize information on topics they want to revisit, track social mentions, or share resources with others. Popular bookmarks rise to the top of the site through sharing and users carefully select relevant tags and titles to best categorize bookmarks.
