About 3 years ago, I wrote about my admiration for Bill & Melinda Gates for their philanthropic activity. Sometime later, Warren Buffett announced that he was promising much of his wealth to charity - and that most of the proceeds were going to the Bill & Melinda Gates foundation.
The new issue of Fortune outlines the collective efforts of Bill, Melinda & Warren to get half the US billionaires to pledge half their net worth to charity during their lifetimes or at death. The expected windfall to the philanthropic kitty? $600 billion. This is a great read & if successful, would transform philanthropy worldwide.
