Google+ introduced Google+ Communities to the Google+.
Public or private membership to support all kinds of groups—from topics and interests to local neighborhoods to regular poker nights
Discussion categories to find the conversations you care about most
The option to start hangouts and plan events with community members
The ability to share with your community from any +1 button across the web
After pages Google plus is taking one more feature from Facebook, the communities. But there are some features like Hangouts can be held between the community members.
