(The Wall Street Journal)  Facebook CEO and creator Mike Zuckerberg plans to set up a foundation to improve education in America.  His first substantial donation will be $100 million to the notoriously poor education system in Newark, New Jersey, marking his debut as a major philanthropist.  Mr. Zuckerberg is very interested in improving education and is particularly concerned with low salaries for teachers, but specific details about how this gift will be spent have yet to disclosed.  Mr. Zuckerberg will announce his donation on “The Oprah Winfrey Show” this Friday.  Facebook, a social networking site with over 500 million international users, is estimated by investors to be worth over $20 billion.
