Warren Buffett pledge as part of the $600 billion challenge

I’ve always had a lot of respect for Warren Buffett, but this article and the philanthropic efforts described in it are unique and humbling.  Definitely read the entire piece; here’s one of my favorite passages:

I’ve worked in an economy that rewards someone who saves the lives of others on a battlefield with a medal, rewards a great teacher with thank-you notes from parents, but rewards those who can detect the mispricing of securities with sums reaching into the billions. In short, fate’s distribution of long straws is wildly capricious.
