Social networking has become part of world culture in the last decade or so. Facebook currently rules the roost, closing in on one billion users, while others such as Twitter and Google+, with over 100 million users each, are very popular and growing. There is also a wide variation of social networks available, from those that are music orientated like SoundCloud to professional networks like LinkedIn. People want to get in touch with others, from catching up with old school friends to making contacts in their field of work, and social media networks allow them to do just that. Inevitably, social media networks have influenced the world of online dating.
