The article reports that Twitter Inc., the world's third-largest social-networking platform, is aiming to get one billion followers. Twitter, whose users send more than 100 million short messages daily, said that it will open to more advertisers after a successful trial with brands including Starbucks Corp. and Coca-Cola Co. The company also redesigned its site in September 2010 to make it easier to post photos, video and maps directly on the page to attract more users.
