As a user of Twitter and business owner myself, I believe that any business general should be actively using Twitter and other social networking sites to promote their business. In a word…”it’s just good business”. Here is a FREE source of advertising that does not only reach people in your city, or town, or state, but gives you the ability to market your product or service worldwide. Not only can you reach current customers and seek out new ones, you also open yourself up to a huge source of customer feedback, and free ideas. This is a great chance for customers to give their opinions on current services or products, and let you know what they would like to see. And it is much cheaper than market research group.
