Google+ Ripples: watch how posts get shared

 
There’s something deeply satisfying about sharing on Google+, then watching the activity unfold. Comments pour in, notifications light up, friends share with friends (who share with their friends), and in no time at all there’s an entire community around your post. Google+ Ripples help people re-live those conversations—both to rekindle that initial excitement, and to learn how posts flow across the network.

 

How  Google Plus Ripples work 

Just find a public post that interests you, and select “View Ripples.” From there you can replay its activity, zoom in on certain events, identify top contributors and much more.

 Google+ Ripples is still experimental

Is Google+ Ripples will be usefull or its just a gadget ?
