Google+
Google+ allows you to develop conversations around shared interests rather then be connected to random people. You can create collections to group your posts together and others can follow particular collections of your posts rather than all. You can also create communities or groups for anyone to discuss or share things.
Why use Google+?
- It is highly integrated with Google search
- Businesses with Google+ profiles may be seen higher in the Google search results
- Status updates can be 10,000 characters and can be targeted to a circle or group of contacts
- Collections is a good way of allowing people to see posts that deal with a particular topic
