People you find on the Internet
Believe it or not, I signed up to online dating site OK Cupid just because I heard that they had very interesting and unique algorithms for matching people. Matches are calculated based on questions you answer, but there’s more to it than that. For any given question (e.g. Which is more important to you, true love or sex?), you choose a single answer, but you can also say which options you want a prospective partner to choose and how important that question is to you. So, for instance, I can specify that it is very important that they answer No to the question ‘Is God the most important thing in your life?’ This all works pretty well. Most of the guys suggested for me were actually pretty good matches.
