For instance, eHarmony users answer a lengthy set of probing questions, aimed at finding one’s true soulmate, which takes over an hour. The cost for one month is $49.95. A Tinder profile, on the other hand, is free at the basic level and takes only a few minutes to setup: “You simply download the app to your smart phone, link to your Facebook account, choose up to six photos of yourself, and write a brief bio. That’s it!”
