People who are looking for a partner in life are always looking for the perfect date, but many of them have a difficult time defining it. They want someone who is attractive, intelligent, outgoing and fun. This sounds fairly definitive, but it does not quite spell out the person they seek. Everyone has their own measurements for these attributes, and no two people look at them quite the same. This has been an issue for centuries, but computers have helped to change the way people define what they seek.
Online dating sites often feature a matching service for their clients, but each person must define exactly what they want. Computers are literal, and giving vague descriptions will not produce any results. That is one good thing about them, and daters are forced to qualify their choices for a good match. The world of dating may never be the same, but perhaps that is best in the modern world.
