"The social network is a collection of different social products. These features include Stream (a newsfeed), Sparks (a recommendation engine), Hangouts (a video chat service), Huddle (a group texting service), Circles (a friend management service) and Photos (Ben Parr - Complete Guide to Google+).
Keep in mind there is a bit of a learning curve as w/ anything new...
Lets take a quick look at the main features of Google+:
- Circles - The closest thing this resembles is Friends in Facebook or followers on Twitter but w/ the ability of who can see what. You the user control which people go in which circle and who can and can't see your posts or even share your posts for that matter. This is a nice feature for those that wanted more control over their posts then simply putting them in public or private on Facebook. Again there are different things to learn such as streaming (aka posting) or "liking" a post w/ a "+1".
- Sparks - Is a recommendation engine (think Bing) built right into Google+ that allows users to "pin" into their profile's sidebar or share right into their circles.
- Hangouts - Probably, one of the coolest features of Google+ is "hangouts" or their 10 way video chat feature. Basically, this is creating a room for people to chat via video. This has a nice visual user interface and integrates w/ YouTube as well for sharing. There is also a group text feature which is handy. The goal for Hangouts is to be much more inviting then the standard one on one video chat (I think they may have found a winner here!!).
