    The way we use the internet haschanged. It is no longer merely a digital reference library. As the internet has grown and the amount of information available has expanded, people have developed a new way of accessing this information in a way that is relevant to them. The ‘new’ internet, or ‘Web 2.0’, is a network of relationships where users interact and share knowledge with each other. Virtual friends become the custodians of knowledge, recommending products and services through their blogs and on other social media sites. By seeing what your like-minded friends find interesting, you are better able to decide what information you wish to ‘consume’.
