It’s pretty ballsy to call your sexting app Poke. That was my first reaction to the news last week that Facebook had launched a clone of Snapchat, the trendy smartphone app that lets you send photos and videos that self-destruct after a few seconds. Like most people born before the 1990s, I’m not a Snapchat user, and I’ve long assumed the worst about the app—that combining cameras; young people; and secret, self-destructing messages could only mean trouble.
