Buffett gives $37 billion to Gates and family foundations

In a letter to Gates and his wife, Buffett wrote: "You have committed yourselves to a few extraordinarily important but underfunded issues, a policy that I believe offers the highest probability of your achieving goals of great consequence."

Gates and his wife said in a statement on their foundation's Web site: "We are awed by our friend Warren Buffett's decision to use his fortune to address the world's most challenging inequities, and we are humbled that he has chosen to direct a large portion of it to the Bill & Melinda Gates Foundation."

this is truly amazing. hopefully it will set an example to other billionaires to do more for charity. this represents 80% of his net worth (so his kids still have what to look for..).
