Google Plus has recently added a new feature to every post: “View ripples“. Click on the drop down menu (arrow down) next to a post and look for the last menue item “view ripples”. In order for this functionality to work a post had to be shared (at least once) by other readers. The result is an instant social network analysis: starting with the original poster as the node in the middle with his outdegree connections indicating each node who has reshared the post out to his or her own network.
Besides the really neat network graphic, Google Plus also offers a few descriptive statistics, such as the names of those who serve as “influencers” in the network and the number of times their own repost was shared, plus a few numbers such as average (chain) path length (the number of times the post was reshared), the longest chain, and the shares/hour. Google calls the influencers in the network “sharing hubs”. The only downside I see right now is that you can’t ripple your own posts. Too bad!
Here is a public post by Pete Cashmore, founder of Mashable.com, including those of his public followers who shared the post and the descriptive statistic at the bottom of the page:
