The concept of Social Capital can be defined as ‘Investment in social relations with expected returns in the marketplace’. The value of Social Capital to global business in 2006, measured as the difference between a business’s market cap and net book value, was $8 trillion. The principle of Social Capital, supported by a growing commitment to one another, the environment, and a healthy desire for capital return is becoming much more mainstream in large part due to the use of Social Media. Social Networks, blogs, podcasts, wikis, shared play lists, Skype, and other forms of social media are all part of a new era of connectivity, interdependence and immediacy where more and more people are realizing what we do to others and to nature, we also do to ourselves. This phenomenon is driving companies to a new level of transparency and authenticity. Furthermore, people are becoming more and more adept at sniffing out companies that are genuinely solving problems against those that are merely attaching their name to a cause to enhance their reputation. The old cause-marketing model of trying to "own" an association with a specific cause can actually generate more cynicism than success. As a result, more and more companies are realizing it is the right time commercially and ethically to reassess their positions and build real market and social capital value by honestly realigning their core brand identity with deep and engaging social and environmental commitments. But more can be done to help these companies along this path, and those companies who have not yet embarked on the journey. How much of their social capital value is due to or can be connected to the use of social media? What is best practice for a company and its stakeholders with regard to driving social capital through social media? Where are the examples?
