The role of social media is critical because it helps to spread cognitive dissonance by connecting thought leaders and activists to ordinary citizens rapidly expanding the network of people who become willing to take action.

More brands are waking up to their social responsibility and doing good work through cause marketing campaigns. Yet too many still go about it the wrong way. I mean 'wrong' in two senses. Firstly, they are marketing ineffectively, and secondly, as a consequence their positive social impact is not maximized.

Let's hope brands recognize that the true power of this technology is not its reach but its ability to communicate substance that adds meaning to our lives. Otherwise, brands will be investing in technology that consumers simply won't buy.

A world in which government is burdened by historic debt, philanthropy has limited resources, and the private sector is only interested in its own personal gain is simply unsustainable.

One of the greatest challenges companies face in adjusting to the impact of social media, is knowing where to start.

Greed has increasingly become a virtue among Wall Street bankers and corporate CEOs in the U.S. Nowhere else in the world do CEOs insist on receiving compensation as high compared to what their employees earn.

Since most corporate competitors have the same problems with sustainability and social reputation, it's worth trying to solve them together.
