Twitter has about 100 million active users, about half of whom sign in once a day. The social media outlet allows businesses, including those in insurance, to stay connected to their customer base and to keep clients updated with industry developments. "Twitter for the average broker is a much bigger investment in terms of making a name for yourself," said Steven L. Johnson, director of social media programs and research at the Fox School of Business' Institute for Business and Information Technology. "The more niche your product is, the more Twitter would be helpful. Then you could be known as the go-to information source."
