If your kids aren’t on Facebook, where are they? Try Snapchat. There’s no need to burn after reading: This app’s files self-destruct. The service is designed for savvy teenagers who don’t want to leave an Internet footprint. Released in September 2011, users can send “Snaps”—photos or videos—that last between 1 and 10 seconds, depending on the limit set by the sender. It already has 100 million users and 350 million snaps sent daily, according to a spokeswoman for the app.
Twenty-six percent of 18- to 29-year-olds with cellphones use Snapchat, according to Pew Research Center, compared with 5 percent of 30- to 49-year-olds and 3 percent of 50- to 64-year-olds. Parents might want to monitor and check in on their kids’ social media activity from time to time, says Kelli Krafsky, coauthor of the book “Facebook and Your Marriage,” but “Snapchat is impossible to check.”
