ShareThis, the popular social sharing widget, has released an update that is currently in beta. The biggest upgrade is the ability for users to share a page's content to more than one destination simultaneously. With a single click, users can share your content via email, Facebook, Twitter, Stumbleupon, Tumblr, LinkedIn and more. This added convenience for the user could be significant - anything that makes content sharing easier should also be on publishers' radars.

Also included in the update is the ability for users to share content without ever leaving your website and the incorporation of custom themes and colors. In the works are updated plugins for Wordpress, Blogger and Typepad. ShareThis claims nearly one million websites use the tool.

You can see an example of the new widget functionality below, and vist the ShareThis website for more details and to test it out.
