NEW YORK (Reuters) – Twitter co-founder Biz Stone said on Monday that the company is developing various add-on tools and services for the businesses and professional users of Twitter, which could create a revenue stream for the company. He said Twitter plans to introduce some of these tools by year end.
But Stone dismissed the notion of selling advertisements on the popular service at this time, even though ad revenue is the main way most Web start-ups manage to stay in business while keeping their service free for consumers.
