Two sites focused on social change: Changemakers and SocialEdge

I have discovered two sites focused on social change that are inspiring and, I think, use technology well to create enthusiasm for social change.  Changemakers.net is funded by the Ashoka Foundation and focuses on catalyzing social entrepreneurship worldwide.   The site is currently providing a forum for solving water problems globally, and  the Smart Commons Mosaic provides a place to share experiences people or organizations have solving these problems in communities.   SocialEdge.net is a platform for discussing and sharing experience in social change.   It is presented by the Skoll Foundation and again provides a forum for discussing and posting successful change management strategies and practices.
