Mark Zuckerberg announces the birth of his daughter by pledging to give away 99 percent of his Facebook shares

Most parents dream of a better world for their children. Unfortunately, most parents are not Mark Zuckerberg and Priscilla Chan, who just announced the birth of their first child — a baby girl named Max.

Fortunately, Zuckerburg and Chan do have the resources to do their part to ensure that Max will grow up in a better world — and the rest of us will also get to reap the benefits! In an extended letter addressed to Max (and posted on Facebook), Zuckerberg and Chan have announced that over the course of their lifetimes, they will give away 99 percent of their Facebook shares — currently valued at $45 billion — in an effort to "advance human potential and promote equality."

"Max, we love you and feel a great responsibility to leave the world a better place for you and all children," the letter concludes. "We wish you a life filled with the same love, hope, and joy you give us. We can't wait to see what you bring to this world."
