商業(yè)新聞:Google+誕生 挑戰(zhàn)Facebook（上）

Google and Facebook are wrestling for pieces of each other's business. Facebook put a move on Google's Gmail by launching its own email service. And Google tried to loosen Facebook's grip on social networking with Google Buzz. That didn't go well. Now, NPR's Martin Kaste reports Google is trying something else. The new social network is called Google Plus, and you aren't allowed to join it, at least not yet. It's small but growing. VP Bradley Horowitz says Google Plus is still in field testing, so invitations have been sent only to a limited number of early adopters and journalists. It's similar to the rollout strategy for Gmail and Google Voice. And if the company is lucky, the perceived scarcity will build up demand, but for what exactly? We created a system that is based on the concept of circles so that I can take my college friends and drag them into a circle called college buddies, and I can take my work colleagues and drag them into a circle called work friends and share selectively the parts of myself with each of those circles that I choose to. In other words, Google Plus is trying to solve the age-old problem of what to do when you're friended by your mom. In a promotional video, Google suggests that organizing your online life into circles may actually help you to loosen up.
