This year's Forbes 400 list is out [3], ranking the nation's most obscenely rich people so they can feel stupendous about themselves. Unsurprisingly, lots of tech celebrities are on the list, and one has taken a huge leap: Facebook [4]'s Mark Zuckerberg.

Zuck jumped all the way to number 35 on the list thanks to the $4.9 billion he added to his fortune, totaling $6.9 billion. That's largely due to new evaluations of his company, which rate its value at around $23 billion, a whopping three times last year's estimate.

By contrast, Steve Jobs [5] is almost destitute. Adding only $1 billion to his net worth in 2009, Jobs is worth an estimated $6.1 billion, which ranks him at a lowly #42. Forbes notes that the majority of his net worth comes from his Disney [6] stocks rather than his Apple [7] stocks--he's got nearly four times as much money from Disney as Apple.

Luckily, Mark Zuckerberg isn't merely sitting on his giant mountain of money, having a sliced money sandwich with money-mustard dressing on seven-currency bread and sipping on a moneyberry milkshake. The Wall Street Journal [8] reports that Zuckerberg is set to announce a $100 million donation to the Newark, NJ public school system this week.

Newark, farming mecca or not [9], is one of the poorest large cities in the country, and its public school system is, on the whole, a disaster. Only half of its students secure a high-school diploma, and only 10% go on to four-year colleges. Zuckerberg is working with Newark mayor Cory Booker and New Jersey Governor Chris Christie to secure a matching $100 million from various private foundations. That $200 million would amount to well over 20% of the Newark public school system's total budget. All of which makes Facebook seem worth its stellar valuation.
