Twitter, Facebook, and other online social networking tools can help nonprofits in various ways, including helping groups reach new audiences to ultimately increase supporters and donors. Twitter is a free online service where users can send real time updates on what they are doing to those who want to receive them. Updates are displayed on the user's profile page. Many nonprofits are using twitter, for example visit Public Citizen's Twitter page and the National Wildlife Federation's page. But many groups are not using them effectively, or are still unsure how to include any online networking tools. To learn more about some of these tools and how to use them, check out this transcript of an online discussion hosted by the Chronicle of Philanthropy. One of the participants, John Haydon, wrote Twitter Jump Start: The Complete Guide for Small Nonprofits.
