Google is sneaky. It has quietly launched a new service that lets people share bookmarks. It is called Google Shared Stuff.
To get started, you drag an "Email/Share" button to your browser toolbar. When you click on the button, you have the option of e-mailing the link or a preview of the Web page you are visiting to someone, sharing it on Facebook, Digg, Delicious, Furl, Social Poster or Reddit, or posting it to a Shared Stuff page.
You can keep track of bookmarks that your Gmail contacts have shared and see popular links, as well as subscribe to feeds for the pages. You also can add comments and tags to the items and upload a profile photo from Picasa.
Google Bookmarks has been around for awhile. This new feature adds the "social media" component that other bookmark services have.
Tip of the hat to the Google Operating System blog for being among the first, if not the first, to report on this.
