What Google+ ripples are all about
I have a page called Phoenix, Arizona Historical Images, where I post old photos of Phoenix, which is my hobby. And if people like the post they will click a +1. If they really, really like it, they will click and +1 and say something like "very cool!" If they really, really, really like it, they will reshare it, and post it onto their Google+ page. And if someone sees it, and in turn reshares it, it ripples.
If you see a reshare when you view activity on your Google+ post, take a look at ripples.
