A recent Social Philanthropy post noted a North Carolina charity that created a "Twitter Table" at an annual fund-raising dinner as a way to use the social network to prompt donors who were not at the dinner to give.

The post has since inspired Gail Hyman, a fund-raising consultant, to think about creative ways for other nonprofit organizations to use Twitter to raise donations and draw attention to their causes.

She offers several suggestions on the blog eJewish Philanthropy.

MyProjects, a Web site run by the cancer charity Cancer Research UK, is designed as a way to give donors a chance to see exactly how their money is being invested.

The site uses a crowdsourcing technique, in which donors have the option of choosing from among 12 research projects that range from specific types of cancer to broader initiatives that work to provide health information to British citizens. Donors can also join or set up a giving group.
