Here’s a great post on ITs, social networking and development agendas:
So, next time someone proposes to throw the latest technological gizmo at a problem or is convinced that marvelous “apps” will definitely cure all kinds of ills in the world, I suggest that you ask: Will ITs help to connect people in ways that facilitate communication and collective action? What communication challenge will be addressed? How do we know if people communicate better, then, they will be in a better position to deal with a problem? What has happened in the past when then-new ITs were introduced? What communication and development challenges could ITs help us understand and hopefully address? These questions should be at the center of “net thinking” for social change and development.
