4. Time Waster
Business Insider reports that social media is the most popular use of the Internet - surpassing email - and smartphones and other mobile devices seem to be the driving force behind this trend since 60 percent of the traffic is from a mobile source. The GlobalWebIndex poll shows that 28 percent of the time spent online is on social networks. With these type of numbers, some of the time spent on social media occurs at work. When these visits are for non-work related activity, it can cost companies money through lost productivity. A report on Forbes states that 89 percent of responders admitted to wasting time on social media while at work.
