Dating sites

During the last lecture of social aspects of new media there was talked about romantic relations online. Most of these romantic relations arise through a dating site.There are general dating sites where people can create a profile with information about their age, gender, length, posture, interests etcetera and these dating sites are accessible for everyone.  Furthermore, there are also dating sites which are focused on a specific group or with the same interests. In the Netherlands are not many of these sites but other countries have the most diverse dating sites. Have you ever heard about Jewish singles, sugardaddie or wealthy men? These dating sites are examples for specific interests or groups. Do you think that it is important that people from the Netherlands also can use these sites to meet other people in this country?
