A few words on the websites/blogs that I find very useful in my area (microfinance, sustainable business models, and social entrepreneurship). 3 sites on microfinance: CGAP for the most thorough coverage on issues of microfinance, Mixmarket, is the best place if you would like to search for microfinance institutions by country or continent as well as look for investment funds that are available, while Microcapital informs about all what is going on in the world of microfinance investments. NextBillion is an excellent site connecting development and enterprise by identifying and discussing sustainable business models that address the needs of the poor. SocialEdge is a platform for social entreprenuers to discuss cutting-edge issues shaping the field, as well as to network and support the growth of social entrepreneurship.
