I've noticed visits from DoJ have started happening in pairs--the same IP address, but two different computers, one using Netscape, the other IE, and within seconds of each other.
As I've explained before, per Site Meter, "If there were no out clicks on the last page viewed, the view time of that page will be 0 because it is unknown how long the page was actually viewed."
So--anybody have any ideas for why two simultaneous visits?
