About Google+ Ripples
Google+ Ripples creates an interactive graphic of the public shares of any public post or URL on Google+ to show you how it has rippled through the network and help you discover new and interesting people to follow. Ripples shows you:Who has publicly shared a post or URL and the comments they’ve made
The comments users added when they reshared a link are displayed in the sidebar of Ripples. If the person’s name is visible in the visualization, their comment will be displayed in the sidebar. Try zooming in and out and moving around to see different comments! (You can also view the comments people made on their reshare by hovering over their name in the Ripples visualization.)
To view Ripples for a public post in your stream, just click the dropdown arrow at the top of the post you’re curious about and click View Ripples.
To view Ripples for a specific URL, open the Ripples dialog, and in the top corner, enter the URL you want to see Ripples for. You’ll see a visualization for all the public shares on Google+ of that URL.
If you find a particularly interesting Ripples visualization, it’s easy to share it with your circles. While viewing the ripple, just copy the URL and share the link in your stream.
