On YouTube, Google reaches out to viewers by broadcasting videos of influential individuals coming by to discuss topics of their respective fields.

Within the channel, located at www.youtube.com/atgoogletalks, you will find videos with presidential candidates who have visited Google, powerful and influential women, well-known filmmakers, and esteemed authors.

Recently, Heather McLeod Grant, the co-author of Forces for Good: The Six Practices of High-Impact Nonprofits, (voted a top 10 book for 2007 by The Economist), dropped by to discuss what makes a non-profit great. (Also see onPhilanthropy's recent article by Julie Fagnani on Google, "Google: Better at Doing Good?")

To find out more about Heather's book, or hear more about her views on measuring non-profit impact, check out Sean Stannard-Stockton's (onPhilanthropy guest writer) podcast at his website Tactical Philanthropy. There, he interviews Heather McLeod Grant and Leslie Crutchfield about their book, but also on several topics including the potential Web 2.0 brings non-profits.
