It’s easy to see why online dating has taken off. It provides you with a seemingly endless supply of people who are single and looking to date. Let’s say you’re a woman who wants a 28-year-old man who’s 5 ft. 10 in., has brown hair, lives in Brooklyn, is a member of the Baha’i faith and loves the music of Naughty by Nature. Before online dating, this would have been a fruitless quest, but now, at any time of the day, no matter where you are, you are just a few screens away from sending a message to your very specific dream man.
