Social Entrepreneurship is hot. Social Entrepreneurs use business as a means of pursuing social goods (rather like an early form of transcommercial enterprise), or, alternately, use entrepreneurial techniques in traditional NGOs.
Now, Fast Company has a whole section devoted to social entrepreneurs: who's doing good work, what the movement means, and how to pick winners from non-starters. As might be expected, FC's focus is more exclusively on businesses, but there's still plenty worth reading here.
For more on people who are using innovation and entrepreneurial ideas to change the work of NGOs, go the the mother-lode of all things socially entrepreneurial, Ashoka. Or, if you'd like to meet and talk with people who are actually engaged in this work themselves, head over to the Skoll Foundation's SocialEdge webconference.
