Installing this module will allow a user to easily add a set of ShareThis.com buttons to the product page, under the product description.
In addition, two widgets are included which do the same, and can be added to a Magento site anywhere that widgets are excepted. One widget displays the standard style buttons, and one displays them in a floating side bar.
The current buttons included are the official ShareThis.com button, and also Facebook, Twitter, LinkedIn, Pinterest, and Email.
