What is AddThis? Well, it is two fold really.

With the AddThis Web Buttons, web publishers make it easier for their visitors to collect content from their websites or blogs, and send it to their favorite destinations, including social media services. The button currently comes in four types: bookmark buttons, feed buttons, product buttons, and podcast buttons. Product buttons, for example, are a very powerful way for web publishers to help their visitors remember and spread the word about the products they sell. With a simple click, visitors can quickly and easily collect information about these products and include it in their shopping research. Web Buttons can be added onto web pages or emails with a simple cut-and-paste. TypePad widgets are also available. Add This also provides statistics showing web publishers what content is collected the most on their website, blog, or email communications.

With a single button, the AddThis Browser Button, web users can collect the content they come across and save it into their favorite bookmarking service, feed reader, shopping service, or podcast reader. The Add This Browser Button is easy to install and easy to use. It works with both Internet Explorer and Mozilla Firefox. With its simplicity, the Add This Browser Button could well become the preferred method for collecting information online.

You can add the button to your website or your browser, and when clicked it will open up this window for you to bookmark the content:

then choose your favorite feeder or social bookmark, that’s it. One click for all.

In case you haven’t noticed, I’ve already added two buttons on my sidebar.
