Parsing the world of sharing into easier-to-digest pieces, Google+ hopes to build a sort of social intranet, where the right content finds the right people.
Here is a view of the Google+ home screen, showing a main stream of all friends' content down the center column; groups of friends, called Circles, run along the left side; with a user's interests, called Sparks, underneath them, giving recent topical news on those subjects.

Instant Upload will send photos and video from your phone straight to Google+. For now, the native app is only available on Android devices. However, Google's Web site says any smartphone can access Google+ through the Web app, and that a native app for the iPhone is coming soon.
Google+'s Huddle feature allows text messages to be sent to a group of people who share a common need, such as making a group decision or setting up a meeting time and place at a restaurant or concert.
