Companies may actually be losing money when they block social networking sites like Facebook. Many companies block access to Facebook because they fear employees will waste time socializing, or share too much information about their company.
These companies may believe they are gaining an edge on employee productivity, but what they’re actually doing is eliminating powerful marketing, advertising and recruiting mechanisms. Facebook is one of the most trafficked sites on the Web and smart companies are taking advantage of that. Social networking can easily segue into social marketing with the right techniques.
