“There are four ways, and only four ways, in which we have contact with the world. We are evaluated and classified by these four contacts: what we do, how we look, what we say, and how we say it”.
Dale Carnegie

Social Media is the biggest   revolution of the century. If the 18^th century brought the Industrial revolution that was about to change forever the face of industry, commerce and economy, the Technology and Information revolution is changing the communication world. As Marshall McLuhan said in his books “The Gutenberg Galaxy: The Making of Typographic Man” and “Understanding Media” we  are now living in a “global village” due to globalization, the internet and the world wide web.
