<p>The 21st century has brought with it many changes to our contemporary society. These changes are expressed in different ways, including the way we communicate, our life style, climate conditions, and short and medium term societal concerns.</p><p><br />In today’s word, the Internet is our primary means of communication. Social media like Twitter are the fastest way to share the news: today, for example, the Mayor elect of Bogota (Colombia) twitted the names of his cabinet members (1). Young people use Facebook as the main way to communicate, and apps such as Skype, Hangouts or WhatsApp are growing in popularity because of their ease and versatility, considering that they can be used in tablets and smart phones (2).
