Ansel Elgort and Kaitlyn Dever are on one side of the tech**logical gap depicted in Jason Reitman's new film Men, Women & Children. In the movie, which debuted at the Toronto International Film Festival last week, parents and their teenage kids find themselves at odds over the role devices and screens play in their lives. We caught up with Ansel and Kaitlyn to ask about their own experiences with social media. Ansel, an online favorite thanks to a number of hit films, including The Fault in Our Stars, turns out to be a big proponent of engaging with his fans -*even though a certain Oscar-winning actress told him it wasn't a great idea.
