Searching for a partner has always been difficult for those who are willing to define what they really want because finding that one person out of millions is a hunt worthy of a tale. For those who choose an online dating service, matching criteria are used to help narrow the field. Users are generally given a selection of those who come as close as possible to being their perfect match, and it is up to the person to make their own connection after that.
Many services tout the number of marriages entered into by couples who have used their service in the past, and this number is seen as a measure of their success. Introducing couples who might be the most compatible is their goal, and it is the means by which they attract customers. It remains for the future to unfold for society to see how many of these couples remain together.
