I am a huge fan of StumbleUpon – the social networking site that lets you set preferences and find site that you might be interested in – and share them with friends!
But as a blogger, I am always interested in how often my pages are Stumbled (added to StumbleUpon’s databases).
Simply drag and drop the “Stumbled?” link to your “Bookmarks Toolbar Folder”. Now, you will have a shortcut on your Firefox Bookmarks Toolbar.
