This short photoslide clip is all about 'Most Popular Social Networking Sites'. The internet has made the world smaller. Information is at our fingertips. Now, with social networking, we have even more access to news and opinions than ever before. It's now entirely common to hear someone ask you to share something on Facebook or to receive breaking news via Twitter on your phone. The world has changed from keeping a Rolodex with lists of contacts to now knowing nearly everything about everyone you've ever met. It's easy to see what your friends ate for dinner, how fussy their kids have been and how they feel about Mondays. As much as people may decry the useless personal information that some people provide on social networks, most people cannot bring themselves to cancel an account for fear that they'll miss out on important information.
