From Facebook's first family, a word of caution

Randi Zuckerberg may owe her success to the online revolution, but that doesn't mean she's entirely in favor of it.

The older sister of Facebook founder Mark Zuckerberg was present at the early development of the most famous and popular social network, and she worked as its marketing director until 2011. Now she's written two books that try in different ways to make people think twice about the amount of time they spend online.

One of them, "Dot Complicated," tells her own story and offers suggestions on privacy and perspective in an online world. The other, "Dot," is a children's story about a girl who discovers the world outside her electronic devices.

From The Guardian:

Both books advocate occasionally switching off connections to social media. While writing the book in Tokyo this year, Zuckerberg did without a roaming data package for her phone. "Gradually, over the course of a month, I loved being unreachable. I saw that the world didn't end if I waited to respond to an email in six hours, rather than six minutes," she told the San Francisco Chronicle.
