Wondering why you'd want to use Twitter? Here's what they say:
Twitter is a communications platform that helps businesses and their customers do a number of useful things. As a business, you can use it to quickly share information with people interested in your company, gather real-time market intelligence and feedback, and build relationships with customers, partners and other people who care about your company. As an individual user, you can use Twitter to tell a company (or anyone else) that you've had a great--or disappointing--experience with their business, offer product ideas, and learn about great offers.
You know that it's good to be close to customers, right?
