Popular social sharing widget provider ShareThis is rolling out a redesigned version and a brand new feature in FastShare which lets users spend more time sharing and less time logging in to social networks/services.

Thanks to support for OAuth (an open standard which allows users to share private details stored on one site with another site without having to re-validate credentials – typically username and password), ShareThis is enabling visitors logged in to any of the sites within its publisher network to automatically see their FastShare options.

Web masters that have implemented current ShareThis widget (using buttons.js code) will be able to access FastShare and the new design elements within 48 hours.
