I'm beginning to learn the importance of social networking sites to the prominence of a brand's presence in the media world. Something as simple as a blog can show the personality of a brand and have a big influence on the future of a person, place or thing. While Twitter, Facebook and LinkedIn are sometimes underestimated by those who use these types of networking sites simply to share photographs and communicate with friends from college, they are an easy and efficient way to create business contacts and find out information about potential competitors.
