Since 2001 the Global Philanthropy Forum annual gathering has been one of the best conferences on philanthropy. It has sold out every year (2007 included).
This year (April 11 -13, 2007 at Google in Mountain View, CA) the conference theme is "Financing Social Change: Leveraging Markets and Entrepreneurship." You can read the conference program here. The Forum makes an edited transcript of each annual conference available on its web site - previous conference transcripts are archived here. The 2006 transcript will be available closer to April, 2007.
The Forum also posts video of its plenary sessions within a few days of the speeches so be sure to check the website during and shortly after the conference. This year, I have the honor of 'live blogging' the sessions, and I'll do my best to make you feel like you're right there learning alongside me. Join me, here and on the GPF site, April 11 - 13, 2007, live from the Googleplex.
