It appears that globally Facebook drove the maximum traffic to other sites followed by StumbleUpon. But if you see the stats for North America, for this month, you will see that web discovery engine StumbleUpon is currently the biigest traffic driver among all social media sites.
Facebook faced a severe drop in traffic in April 2011 when at the same time StumbleUpon traffic shot up.
