Google is trying once again to challenge Facebook's domination of the social networking business. Its main social networking site "Orkut" is very popular in Brazil, but in the rest of the world, Google trails Facebook.
But the company has a new attempt to catch up.
The new social network is called Google Plus, and you're not allowed to join it. At least, not yet.
"It's small but growing," says Bradley Horowitz, who oversees Google's communications products and social applications.
He 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 roll-out strategy for G-mail and Google Voice. And if the company is lucky, the perceived scarcity will build up demand — but for what exactly?
"We've created a system that's 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 that's called 'work friends.' And I can share selectively the parts of myself with those circles that I choose to," he says.
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 promises that organizing your online life into Circles may actually help you to loosen up.
Facebook allows users to do something similar, with an option called "groups." But some users complain the feature is clumsy to manage.
Google Plus, on the other hand, puts Circles up front. Whenever you upload a photo or a bit of news, Google checks who you intend to see it.
Richard Esguerra, of the Electronic Frontier Foundation, says the company seems to be trying to recover from privacy controversies involving its earlier social networking efforts, like the ill-fated Google Buzz.
"They're trying to fix a lot of different things about their own approach to social networking and privacy," he says. "And also about the general social networking model, and for now I think we're seeing a good start."
Google is also promising to let you move your information out of Google Plus, if you decide to, and Google says it will let you delete your information from its servers — a promise Facebook has never made.
