I found this on Beth Kanter’s blog and it seems to be from NTEN confernence 2007. Author names are in the show. It has some great examples of ways that not-for-profits can use social networking sites. It lays out clearly the argument for using “web 2.0″ apps, including some fantastic stats. It only really goes into Digg and Stumpleupon as  specific examples, but it lays out really great tips for actually using them. The interesting thing is that it is clear that both are going to take time to really become effective. There is a relationship that has to be developed with the potential audience in using these and that takes time. Whether your organization has the time or not, it’s an effective read on what should be done. Of course, my bias is that you should be using these tools, but there is a commitment required.
