Regarding the Zuckerberg announcement.

I was reading the announcement that Mark Zuckerberg and Chan announced via Facebook. The news is that they would be donating 99% of their Facebook shares to charity. And I was very curious to see what percent of their wealth that was, and thought you guys might be interested too. Zuckerberg said he would be giving away $45 billion dollars, but how much of their wealth is that actually? We need to find out how much they're worth. According to Forbes, they're worth $47.4 billion. So they would be giving away 94.7% of their wealth. Truly admirable, and I applaud them!
