Even Mark Zuckerberg's sister is having Facebook privacy issues.
Callie Schweitzer, Vox Media's marketing director, tweeted a photo on Christmas Day of the Zuckerberg family standing around a kitchen island while testing the new Facebook "Poke" app.
Problem was, the photo was meant to be private — Randi Zuckerberg intended to share it with "Friends Only" on her brother's behemoth social network.
Schweitzer said she subscribed to Zuckerberg's public feed on Facebook and, when she saw the photo pop up, she figured it was public.
"Not sure where you got this photo. I posted it to friends only on FB," Randi Zuckerberg tweeted at Schweitzer.
