At the Clinton Global Initiative meeting, Bill Clinton thanked Eric Schmidt for Google's efforts in crisis response, calling out Google Person Finder in particular.
"I'm particularly grateful, as I said, because of this Person Search effort that Google did in Haiti. There's no telling how many people's lives were actually saved and how many people's misery was actually lessened, because of the information that Google could give to a country that otherwise had no sophisticated identification system, and could not have had a sophisticated disaster recovery system because of its level of income and development." —President Clinton, September 21, 2010
His expression of gratitude was a bit of a jumbled mix of Google's contributions in Haiti (of which I consider the satellite imagery to have been by far the most valuable), but it's still a thrill to hear him talk about "Person Search".
