If you are running a website, an e-commerce store, or any sort of business, you need an online presence in social networks. This comes as no surprise to anyone. However, besides being aware of your brand on these sites, responding to customer complaints, and reinforcing positive feedback, Twitter also allows you to reach out to new customers, one at a time. Does that sound like a lot of work? Yup. If it means you sell one more item or sign-up one more user, is it worth it? Absolutely.
Every customer counts when you are starting off!
