Zuckerberg's sister to launch new social media

Randi Zuckerberg, Facebook’s director of marketing, is leaving the company to launch a new social media.

Randi, who is the sister of Facebook co-founder and CEO Mark Zuckerberg, is planning to start a new media firm called RtoZ Media (clearly a play on her name) that will help businesses become more social, Zdnet.com reported.

“We can confirm Randi has decided to leave Facebook to start her own company,” a Facebook spokesperson said in a statement. “We are all grateful for her important service.”

Randi further confirmed the news via her Twitter account.

“It is with mixed emotions that I announced my departure from Facebook today to launch my own initiative," she said.

Randi has been a high-profile and charismatic personality both inside the social networking company and in Silicon Valley, according to All Things Digital, which also obtained Randi’s resignation letter (embedded in full below). She has been on maternity leave for the last three months, after having her first child, and being away from the rapid-fire pace at Facebook reportedly gave her time to reflect on what she wants to do in the next phase of her career.

Most recently, Randi was quoted as saying she thinks “anonymity on the Internet has to go away.” Given that her brother has similar views, it is likely her new company will be very closely tied to Facebook, rather than Google+ or Twitter.
