Mostly businesses use social media to find and communicate with clients. But it is a great distraction to employees, who may show more interest in what their friends are posting than in their work tasks. Wired.com posted two studies which demonstrated damage to productivity caused by social networking. Nucleus Research reported that Facebook shaves 1.5% off office productivity while Morse claimed that British companies lost 2.2 billion a year to the social phenomenon. New technology products have become available that allow social networks to be blocked, but their effectiveness remains spotty.
