Although it doesn't take more than a few seconds to check out a community before hitting that "Join" button, those who like to click things on impulse will enjoy this recent update to community suggestions. Communities that require permission before joining will have an "Ask to join" button on the suggestions card.
To view what communities Google+ is suggesting you join, go to the navigation menu and select Communities (or just click here). The "Discover communities" category is underneath the ones you've joined or are a moderator of. There's not much else to it, so happy joining I guess?
Will this make for a rise in membership across Google+ Communities or not? Let us know your thoughts in the comments!
Thanks for reporting this in our community +Laurence Eckert
