Create private communities
Gather real-world groups of people like your basketball buddies, fellow classmates and family. If you find yourself sharing regularly with the same core group of people, communities are a fast and fun way to stay in touch.
Join public communities
No matter what you’re into, there are people on Google+ you can talk with about it. Search for public communities around the topics you’re passionate about and join the conversation. You’ll be learning new things and making friends in no time.
Get friends involved
Communities are even more fun with the right people. Use the ‘Invite’ link to bring friends into the conversation, or share the communities you like publicly on Google+.
Share how you want, when you want
There are lots of way to share with your communities. Get home welding tips from your DIY pals in a hangout, share restaurant reviews with fellow foodies, or use Google+ Events to plan your next block party. You can share with communities from anywhere you find Google+: on YouTube, Google Maps, or through the +1 button on sites across the web.
