Forbes' growing list of billionaires continues to expand with heavyweights in the tech industry, including a strong presence from several individuals who owe their wealth to Facebook. Founder Mark Zuckerberg now sits at number 52 on the list, after his estimated worth skyrocketed from $4 billion last year to $13.5 billion.
Co-founder Dustin Moskovitz also made the list, with $2.7 billion giving him a place near the middle at number 420. Further down the line, co-founder Eduardo Saverin ranked in the 700s with $1.5 billion estimated worth and investor Peter Thiel achieved the 833rd spot with $1.5 billion.
Aside from the relative newcomers, the 2011 list was still filled with a variety of tech veterans. Mexico's Carlos Slim held his spot at the top of the list after adding $20.5 billion to his growing fortune, while Bill Gates maintained second place with $56 billion in estimated worth.
Google's Larry Page and Sergey Brin both placed near the bottom of the top 25, as both have achieved $19.8 billion in estimated worth. Apple co-founder Steve Jobs made a comfortable gain of $2.8 billion from the 2010 list, helping to boost his position from number 136 to the 110th spot.
