Mark Zuckerberg's sister Randi accidentally shared a private family photo, apparently confused by or unable to grasp Facebook's privacy settings.
How's that for the definition of irony?
Randi Zuckerberg, the former head of marketing for Facebook and the executive producer of Bravo's reality series Silicon Valley, posted the above photo on Facebook.
The candid family picture is of Randi and her family (including sister Arielle Zuckerberg and Facebook CEO Mark Zuckerberg) reacting to the new Poke app.
The problem arose when Callie Schweitzer, director of marketing and projects at VoxMedia, saw the photo on Facebook, but posted it publicly on Twitter.
