Though Zuckerberg is reportedly worth billions of dollars, you wouldn't know it from his style. You can usually spot the Facebook CEO, known for dressing casually, sporting a hoodie or, lately, his signature grey t-shirt.

Just six days after TheFacebook.com launched in 2004, three Harvard seniors who helped Zuckerberg build code accused him of intentionally misleading them into believing he would help them build a social network called HarvardConnection.com.

Who's more powerful than Osama Bin Laden and Oprah Winfrey? That's right, Zuck is, according to Forbes. This year he made his debut on Forbes most powerful people list at number 40. At only 26 years old, he's got plenty of time to edge out Bill Gates (No. 10) and Steve Jobs (No. 17).

Security

Security and privacy go hand-in-hand at Facebook, and Zuckerberg has endured his fair share of problems related to both. First there was Beacon. Then a string of privacy breaches.
