MetroChannel is based on the premise: Where there is smoke, there must be fire. In other words, if some site or blog is popular, it might be worth checking out. But should we enter a site in blind faith? The Online Shadow Economy is not in a mood to spare anyone. So it is a good idea to get help from the online community i.e other surfers who have visited and rated over 20 million websites so that we know which ones to avoid and which ones to trust.
