In a new study of social behavior across devices, ShareThis ( has revealed important insights into what people are sharing, on which devices, and the social networks they are sharing to the most.
The cross-device research compared 4.9 billion social patterns across desktop web and 1.2 billion social patterns across mobile web. Key findings include:

° The iPhone is the most social device: users are three times more likely to share content via their iPhone versus the desktop and one and a half times more likely to share on an iPhone versus all other mobile devices.

° Sharing activity on mobile is dominated by Facebook, Twitter and Pinterest: Facebook accounts for 60 % of sharing on mobile and Pinterest is nearly three times more represented on mobile than on desktop. Most email sharing happens on the desktop but rarely on mobile.
