Lost productivity on Social Networking

I was always sure that the obsession (or maybe the addiction) of some people with their online social networks is costing business money and productivity. How much this cost is was not sure until MyJobGroup publissed the results of a UK survey concluding that "Social Media Costing UK Economy up to £14billion in Lost Work Time". Interesting findings bringing once more the often discussed in this blog subject of organizational guidelines for the use of the Internet during work time (but also outside work time if ) to the attention of businesses.
