P2P Donation Finance
From Melanie Swan at http://www.melanieswan.com/social_finance.html
"Fans are financing bands at Sellaband, movies at A Swarm of Angels, and citizen vlogging at HaveMoneyWillVlog (via an easy-to-use crowd finance Wordpress plug-in which also lists the deliverables and a feedback loops for on-project progress). Austin-based Fundable is a clearing house crowd funding site suggesting project financing for individuals, non-profit organizations, relief efforts and software development projects on its platform."
