EVEN Mark Zuckerberg's family can get tripped up by Facebook's privacy settings. A picture Zuckerberg's sister posted on her personal Facebook profile was seen by a marketing director, who then posted the picture to Twitter.
THAT did not sit well with Zuckerberg's sister, Randi, who tweeted at Callie Schweitzer that the picture was meant for friends only.
Ms Schweitzer replied by saying the picture popped up on her Facebook news feed.
Ms Zuckerberg said Ms Schweitzer was able to see the picture because they had a mutual friend. Those tweets have since been taken down.
