Google starts its Google+ project with five main features. What are they and why are they?

Circles
Circles will allow sharing your content with others in a more real-life oriented way. Don’t we behave differently in different occasions in the real world? Not many should oppose. And that is why Google invented its Circles. Thanks to this feature one can easily share one thing with best friends and other with colleagues, parents, boss and whoever else should be considered.

Hangouts
Allows you to chat with many at the same time, just inform your specific friends or the whole circles that you’d like to meet them via Internet (using your pc camera). As it’s stated on Google+ project website Until teleportation arrives, it’s the next best thing.

Instant Upload
Makes sharing your photos/movies a lot easier. Instant upload means that you don’t have to bother about sending your stuff from a cell phone to your computer and further. Once you enable the feature, your photos are uploaded automatically to your personal album in Google+. All you need to do is to decide who to share your content with.

Sparks
This feature is intended to help you finding interesting content in the Internet. May be described as a personalized search engine thanks to which you always find what you are really interested in.

Huddle
Your thumbs will thank you (for using Huddle) says Google+. Simply, Huddle makes your multi-texting easier by grouping all the conversations into a group chat. Never again should you send the same info to many and then response to each individually.
