On a recent Sunday night, Liz Paul was tired. She'd worked in the morning, spent a full day with her family and she did not feel like going out for her daily jog.

"I tweeted out, 'Well, it's 9 p.m. on Sunday and I didn't work out,' " she says, "I really shouldn't go run in the dark should I?"

The response was immediate. The network of people Paul is relying on to help in her battle to lose weight chimed in with advice. Some tweeted back, "Yes, get out and run." Others offered alternatives like a video workout. But everyone said, "Do something!"

This week, the Supreme Court agreed to hear the case of a man on Facebook who threatened to kill his wife.

In 2010, Pennsylvania resident Anthony Elonis got dumped, lost his job and expressed his frustrations via the Internet.

"He took to Facebook as a form of, what he says, a form of therapy," says criminologist Rob D'Ovidio of Drexel University, who is following the case.

Is It A 'True Threat'?

If Vincent van Gogh, Frida Kahlo or Romare Bearden were alive today, would they have loved the selfie?

"Selfies are just a way to show that you are part of the world," says NPR's Social Media Project Manager Kate Myers. "Here I am, and the world is more interesting because I'm in it."

The word "selfie" rose to new prominence this week after it was unanimously picked as word of the year by Oxford Dictionaries.
