“It’s a product of the growing normalcy of using social media apps,” says Moira Weigel, author of “Labor of Love: The Invention of Online Dating” (Farrar, Straus & Giroux, 2016).“I was on a date with a guy who turned out to be a convicted felon.Another guy claimed to be 38 but was at least 60,” says Kate, a 33-year-old government analyst from Washington, D. “Sometimes I will go on a date to see how bad it’s going to be.” The fact is that online dating is, well, complicated.If you find your life partner on your first date, the site doesn’t make much money off you.Our survey found that among respondents who stopped online dating, 20 percent of men and 40 percent of women said they did so because they didn’t like the quality of their matches.And we found that the free sites generally did marginally better than the paid ones, presumably because they offer a better value.
