Computerworld, on Google+:
However, what Google hopes will set its social network apart from Facebook and the smaller social networking services is that Google+ is set up to allow users to communicate within separate groups of their online friends. Instead of posting an update that goes out to everyone, Google+ enables users to create “circles” or groups, such as a user’s poker buddies, college friends, work colleagues and family members.
Now a user can communicate separately with each group.
“The “circles” idea makes a lot of sense,” said Ezra Gottheil, an analyst at Technology Business Research. “It’s smart, and while you can do something similar in Facebook, it’s not Facebook’s main thing. It’s not as easy to do.”
You share different things with different people. But sharing the right stuff with the right people shouldn’t be a hassle. Circles makes it easy to put your friends from Saturday night in one circle, your parents in another, and your boss in a circle by himself, just like real life.

“In real life, we have walls and windows and I can speak to you knowing who’s in the room, but in the online world, you get to a ‘Share’ box and you share with the whole world,” said Bradley Horowitz, a vice president of product management at Google who is leading the company’s social efforts with Vic Gundotra, a senior vice president of engineering.
