Twitter now provides a business guide to help business users effectively market and communicate. One of the best tools that I found is the question/search option. Here are the instructions.
Go to your twitter home page. Look about 1/2 way down on the right side of the page. Enter a topic, brand, item name, or phrase in the search field. Click the hour glass. What will be returned are messages related to your subject matter. Now let's say for example that you sell Costa Rican Coffee. Chances are you will find someone that is in need of coffee or maybe a twitter friend that is drinking another brand that might be interested in hearing more about your coffee. The possibilities are endless!
For more tips on ways to use twitter go to the Twitter 101 Business Guide.
