Only for a couple of years social networks like Twitter or Facebook exist, yet they are already part of the daily lives of 950 million users worldwide. Being online is in! Taking care of your social life never seemed to be so easy. But is all this really new?
Up till then friends in other countries or even continents were a plane trip or expensive calls away. Now we can text them in every minute of our day or can even skype with them during our evening routine in our own living room. More or less for free, of course.
