ProfileIt all starts with your profile. Choose what people find when they look for you and include things like what schools you’ve gone to, what companies you’ve worked for, and how people can get in touch with you.
CirclesFinally! Circles make it easy to organize your online social world by putting different groups of friends and team members in separate lists, family in another, and whatever other groups you dream up -- then easily post different updates to each circle. You can create as many circles as you want, make each as large or small as you want, and change (or abandon) any of them whenever you want.
HangoutsHangouts let up to ten people have a video chat together using this shared space for anything from study sessions or club meetings to collaborating with colleagues all over the world to holding foreign language labs with several students at once. You can share your screen or add a Google Doc to get even more done with your team.
StreamYour Google+ Stream is the place where you publish updates, pics, links, news, and events. It’s also the place to see all the posts, photos, videos, links or location markers that people in or out of your circles have shared with you. And you only have to see comments and links from people whose posts interest you; Google+ lets you easily select the sources of your Stream.
MobileYou don’t spend all day in front of your computer, but you probably carry a mobile with you when you’re on the go. Google+ brings your Profile, Circles, Stream, and Hangouts to your mobile and adds in some extras like location check-ins, Instant Upload for photos, and Messenger for quick group chats.
SearchType what you’re looking for into the Google+ search box and your results will include your own posts, trending topics from across the web, and people (whom you can add to your circles), all at the same time. You can then save that search for easy future checks of what’s new in this particular area of personal obsession.
