The remainder of the top 10 is comprised of (3) Twitter, (4) Pinterest, (5) LinkedIn, (6) Yahoo! Answers, (7) Google+, (8) Tagged, (9) Tumblr, and (10) Reddit. Even though all of these sites have less than 2% of total social media visits, over the course of a year, that translates to hundreds of millions to several billion visits each.
The growth of social media has transformed business (Kodak was a top brand for many decades, until digital photography replaced film photography), weather (Twitter feeds and comments often were the quickest way to get updated information during Hurricane Sandy), news (real-time updates during the Boston Marathon and the days that followed led to thousands of leads as well as inaccurate reporting at times), nations (the change in Egypt is just one of many examples), and communications (text messages and video chat have supplanted "snail mail" to a great extent). Despite some challenges, the use of social media is now an integral part of our daily lives,and will be so for the foreseeable future.
