According to the New York Times, “Three weeks after Curtis Kimball opened his crème brûlée cart in San Francisco, he noticed a stranger among the friends in line for his desserts. How had the man discovered the cart? He had read about it on Twitter.”

“For Mr. Kimball, who conceded that he “hadn’t really understood the purpose of Twitter,” the beauty of digital word-of-mouth marketing was immediately clear. He signed up for an account and has more than 5,400 followers who wait for him to post the current location of his itinerant cart and list the flavors of the day, like lavender and orange creamsicle.”

“’I would love to say that I just had a really good idea and strategy, but Twitter has been pretty essential to my success,’ he said. He has quit his day job as a carpenter to keep up with the demand”

“Much has been made of how big companies like Dell, Starbucks and Comcast use Twitter to promote their products and answer customers’ questions. But today, small businesses outnumber the big ones on the free microblogging service, and in many ways, Twitter is an even more useful tool for them”

‘For many mom-and-pop shops with no ad budget, Twitter has become their sole means of marketing. It is far easier to set up and update a Twitter account than to maintain a Web page. And because small-business owners tend to work at the cash register, not in a cubicle in the marketing department, Twitter’s intimacy suits them well.” the story said.
