But the Google+ project will be different from Facebook in one significant way, which Google hopes will be enough to convince people to use yet another social networking service. It is designed for sharing with small groups — like colleagues, college roommates or hiking friends — instead of with all of a user’s friends or the entire Web. It also offers group text messaging and video chat.
“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.
