Google+ social network home page just like Facebook consists largely of a news feed or a ‘Stream’. The Stream is organized a little bit differently to Facebook though- stuff that you’ve hit +1 on commented on previously will rise to the top of your feed if there is a new comment. So Google knows that you are interested in becoming more visible.
Like Facebook, you can make a status update, or share photos, video and your location. Unlike Facebook, you don’t have to do it on your own profile to make an update. There is a drop-down ‘Share’ menu in the upper right corner which allows you to share from any Google+ page. So you don’t have to open a new tab to share something, or navigate from the page you are using.
There is another menu on upper right for notifications. This works similarly to Facebook in that it changes colour when you have a notification, and drops down when you click on it. Unlike facebook, you can reply to comments within that menu. So you don’t have to navigate away from whatever you are doing.
Circles: Google reckons that ;people have different “social circles”. When you add someone on Google+, you put them into at least one circle using a drag and drop down system. Sometimes you might want someone in more than one different circle, ‘family and ‘friends’. You just need to drag and drop into a second circle.
Categorizing people into groups can be done on Facebook, but it is hidden within Facebook’s settings. Google+ makes creating those filters easy, so you don’t have to share anything with anyone you don’t want to. Every time you share something on your Stream, you get to choose which people to filter in or out.
Sparks: You can search for anything that interests you, and any Google News that applies to that interest will show up in your Sparks news feed. In short, Google+ is doing some simple keyword and tag search
Hangout: is Google’s video chat feature. When you start a Hangout session on Google+ , it starts you default webcam and broadcasts video to your circles. It opens up in a pop-up window. You can invite people to join the video chat.
Google+ Android App: Android users can download an app to assist them while they are away from their keyboard. It has just five icons on the main screen- Stream, Huddle, Photos, Profile and circles. There is a bar across the bottom of the screen that tells you if you have any notifications.
Using Huddle from the Android app is a handy way to communicate with a group of people- it is basically a reply to all email function.
