David Wilcox is maintaining a parallel wiki on the use of social media and Web 2.0 in nonprofits that has additional information. David's site is developing as part of his ongoing efforts with nonprofits to integrate social media, so he's collecting a library of resources that may be especially helpful to nonprofit technology stewards, those people in an organization that are helping it make good use of new tools.
Check out David's wiki and his blog, Designing for Civil Society.
