We all know how important networking is, there is a saying "its not that you know but who you know"
So a background on how social networking has evolved. Some times is hard to imagine the days where you can just take a picture and share it with all your friends or type in somebody's name and be able to find the online, but things have change dramatically.
Some of the ideas of social network theory are found in writings going back to ancient Greeks.
In late 1800s both Emile Durkheim and Ferdinand Tonnies foreshadow the idea of social networks in their research of social groups.
Social groups has been defined as two or more humans who interact with one another, share similar characteristics and collectively have a sense of unity.
As we know social network on the internet is already the norm, for example people are on Facebook, Twitter and more. Web-based social networking services make it possible to connect to people who share interests and activities across borders.
Facebook it self and other social networking tools have become so large that they have become objects of scholar research.
The other fact that I would like to mention here is that there are reality shows in which people meet face to face through the show. For example 'Come dine with me' which is a program brocasted in the UK for a number or years. In this show a number of strangers meet for dinner everyday of the week to each other houses.
