One of Facebook's earliest employees, Randi Zuckerberg, sister of CEO Mark Zuckerberg, resigned from the social networking company. Randi "is leaving her position as director of marketing at the Palo Alto-based website after six years with the company," reports the Oakland Tribune.

Randi will leave the company to launch her own business, called RtoZMedia, "that will launch (her) own innovative programming and work with media companies to develop their programming in new and more social ways."

Like her brother, Randi also attended Harvard. She wrote Spark Your Career in Advertising and, prior to being a Facebook star, appeared as a panelist on Forbes on Fox. Most recently, though, she famously claimed that anonymity online "has to go away."
