Have you heard of “Google+ Ripples?” I hadn't either, until today, thanks to Neil Patel at QuickSprout.

According to Google,

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 

How a post or URL was shared over time

Statistics on how a post or URL was shared

You can read more about Google+ Ripples here. It looks like a very interesting concept.
