"Are you guilty of costing your employers \"billions\" of dollars in productivity with your Facebook addiction?  A recently released study of workers in Australia thinks you may be.\nAn Internet security company, SurfControl, looked into the issue, and it estimates that Australian employees spend approximately one hour a day on the social networking site.  Using that number, they come up with the slack time costing employers approximately $5 billion Australian ($4 billion US) a year in lost productivity.\nHow they reached this mysterious number is, just that, a mystery.  The study lists that there are 800,000 businesses in Australia, and they are estimating one slacking employee per company.  A problem with this estimate is that Facebook only currently lists approximately 224,000 members from Down Under, and then you still have to assume each one of those people is a very active user of the site.\nOf course, the fact that this firm sells a web and email blocking system may explain some of it."^^<http://www.w3.org/2001/XMLSchema#string>
