I just found a very exciting way to "monitter" what consumers are saying about your business. It's located here: http://www.monitter.com.
You can set up search fields and geo locate tweets that have been made about your business or trends you follow in your business.
This is exciting because this gives you an opportunity to respond to either positive or negative feedback with super speed. This is not about selling a consumer but engaging with them on their turf.
Imagine building a relationship with a customer long before they have a need for your product or service. How powerful.
Let me know what you think about http://www.monitter.com.
