Do you remember the time when you found this really cool website and sent an email to all your friends with the link? These days, instead of sending an email, you can hop onto social bookmarking sites and share that cool website link with thousands, or even millions, of net users. Social bookmarking is a method for Internet users to share, organize, search, and manage bookmarks of web resources. Unlike file sharing, the resources themselves aren’t shared, merely bookmarks that reference them. Via these sites, news can become viral, either beneficial or detrimental. The following is the list of the top four social booking sites: The king of the hill, Digg is a social news website made for people to discover and share content from anywhere on the Internet, by submitting links and stories, and voting and commenting on submitted links and stories. Voting stories up and down is the site’s cornerstone function, respectively called digging and burying. Many stories get submitted every day, but only the most Dugg stories appear on the front page. Digg’s popularity has prompted the creation of other social networking sites with story submission and voting systems. Delicious (formerly del.icio.us, pronounced “delicious”) is a social bookmarking web service for storing, sharing, and discovering web bookmarks. The site was founded by Joshua Schachter in 2003 and acquired by Yahoo! in 2005. It has more than five million users and 150 million bookmarked URLs. It is headquartered in Sunnyvale, California. Reddit (stylised “reddit”) is a social news website on which users can post links to content on the Internet. Other users may then vote the posted links up or down, causing them to become more or less prominent on the Reddit home page. It is pronounced, “ read it.” Mixx is a user-driven social media web site that serves to help users submit or find content by peers based on interest and location. It combines social networking and bookmarking with web syndication, blogging and personalization tools. Mixx has received partnerships with a growing list of online publishing outlets including CNN.com, USA Today, Reuters, The Los Angeles Times and The Weather Channel.
