Perhaps the most powerful lesson other brands can learn from Nike is the need to act in accordance with the reality of the world we live in.

Non-profits must become deeply engaged in the ways that their donor communities are using social technology.

Through their own actions, customers can hold companies responsible to higher standards of social responsibility. Through collective action, they can leverage their dollars to combat the force of those investors who myopically pursue profits at the expense of the rest of society.

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.

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.
