If I asked ten people what is relevant information I would get 10 different answers. That is because what is relevant to each of us at any given time will be unique to the individual. We may care about the same topic such as a possible acquisition of a large company by a competitor, but I may be concerned with the product availability implications and you might be looking into the economic effects of the area surrounding the acquired business. Just type the company name into a search engine and you will find a lot of information but much of it might not be relevant to you. You might as well grab a cup of coffee and settle down for some serious research or you can take your search to the next level to find relevancy.
In the content delivery business, we tend to think of content – not necessarily news – as existing in just a few states – important, relevant and irrelevant.
