MARKETWATCH - Aug 14 - The flap between Tinder and Vanity Fair misses a larger point. Nancy Jo Sales, the author of the recent article in Vanity Fair titled: "Tinder and the Dawn of the 'Dating Apocalypse'", tweeted data from GlobalWebIndex, which alleged that 30% of Tinder users are married. Tinder responded that only ~1.7% of its users were married. But most married people lie about their relationship status. 54% of online daters said dates have "seriously misrepresented" themselves in their profiles, according to a 2013 study by Pew Research Center. People tell lies — big and small — because it’s the norm, says Mark Brooks, a dating-industry analyst and the editor of Online Personals Watch. "It's the norm because it's competitive, and it's an easy way to get ahead. But it's no way to start a relationship. I've always encouraged people to ditch dates fast when they show up and they’ve clearly and outright lied."
