Social Traffic Monitor is a plugin for Wordpress blogs that monitors your blog traffic for activity coming from social news or bookmarking sites. When someone clicks on a link to your blog on one of the major social news or bookmarking sites (currently Digg, Netscape, Reddit, Newsvine, Fark, Slashdot, Del.icio.us, and StumbleUpon), the plugin begins to log the visits to that page. This data can then be displayed in the form of a graph of visitors per hour.
