You know all those share buttons across the Web? They are getting more and more social . What I mean by that is initially they were used to share stories or content mostly via email on a one-to-one basis, but over the past year or so services like Facebook and Twitter have been overtaking the way people use those buttons to share stories, videos, images, and links. The way most people interact with these button is through widgets on publisher's sites. But one of the largest sharing button networks, ShareThis , is about to turn that around and introduce a Share Stream which shows you what your Facebook friends are sharing across the Web. Soon your Twitter followers will be added as well (at launch you will only be able to see what everyone is sharing across Twitter).
