Google+ has many interesting features like Circles, Stream, Huddle and Photos. Circles lets you share things within a select group of people.
Stream is much like the Facebook News Feed, allowing users to share photos, videos, links or their location with friends. Stream gives you a live timeline of updates from your friends, not unlike what Facebook's news feed does. And “Hangouts” will attempt to bring a level of spontaneity to multi-person video-conferencing.
Charlene Li, founder of Altimeter Group, a social-media advisory firm, says :
"Google+'s goal is not to replace Facebook. Key thing here is that going against Facebook directly is suicidal. Google has found a seamless formula with more structure. It really is the plus part. It is extending Google's communication platforms into a unified sharing platform."
One of Facebook’s weaknesses is its privacy practices, which have come under attack many times for being confusing, ever-mutating and self-serving. As Facebook and other social networking sites are constantly battling privacy issues, Google + offers its users to selectively share what you want, to whom you want. Facebook’s privacy controls remain difficult to navigate, despite efforts at simplification.
According to comScore, In May, 180 million people visited different Google sites compared with 157.2 million on Facebook. But Facebook users viewed 103 billion pages and spent an average of 375 minutes on the site, while Google users viewed 46.3 billion pages and spent 231 minutes."
The "Like" Button of Facebook and "+1" button of Google+ uses in different website and blogs.
Facebook also making money from advertising. Facebook is now displays more “display ads” than any other company on the net. But for now, Google says there’s Google+ will be ad-free.
