It is very hard to define social entrepreneurship.It can be any venture that contributes positively to change the society in better. It normally requires some sort of market approach, a certain level of sustainability and a return on the investment in form of income generation. We would like to stick to these basic principles in this section although contributors can write in Social Capital and Grass Roots democracy and Civic Ventures sub category about other forms of social ventures or "civic ventures" as defined by Stephan Goldsmith in its inspiring book "The Power of Social Innovation".
