'social entrepreneurship'

Normally, entrepreneurs had two choices of organizational structure when designing a start-up:

• For-profit;
• Non-profit. 

Often, people consider the distinction between the two as good versus wrong things. A non-profit’s mission is to support a social cause. That’s good. A for-profit’s mission is to maximize shareholder wealth. That’s bad. (this is one of the reasons for the crisis).
A social entrepreneur is someone who recognizes a social problem and uses entrepreneurial principles to organize, create, and manage a venture to make social change. In other words, rather than bringing a concept to market to address a consumer problem, social entrepreneurs attempt to bring a concept to market to address a social problem.
I think that one of the most important thinks its that the social entrepeneur adopt a mission to create and sustain social value.
I found some scheme where resume some of this points.
