Twitter Doesn't Sweat the Profit Margin

Twitter, a unique blogging service that lets its users update every minute detail of their day using a computer or cellphone, is steadily growing in popularity, but founder Biz Stone isn't worried about making money from the site yet. With millions in venture capital stored up, Stone is more focused on Twitter's infrastructure and design than on its business model, Portfolio reports.

Twitter is clocking 2 million users a month, 10 times more than in April 2007. The site recently caught the attention of news sites when its users reported the California earthquake 10 minutes before the AP. One user simply updated: "earthquake." Whether the site will start reaping profits from ads or another stream is merely a "distraction" right now, says Stone. (More Twitter stories.)
