Is it possible to measure the ROI value of social networking sites?

Can you measure the ROI (return on investment) value of the time your employees spend exploring social networking sites like MySpace and Facebook? Is it worth the staff time to develop content on all of these various sites? If you’ve ever pondered these questions, you might want to try out the Social Network ROI Calculator. It’s fairly complex and you need to know a fair amount of information about your organization’s operating costs, staffing, and outreach and/or advocacy campaigns.
