I can't remember which one it was, but one of the ATS review podcasts with SO and Springer goes into this in a little more depth.
They mention a few IP's that have visited the site, i remember the DoD being regular visitors and the Pentagon had paid a few visits.
I'd be more concerned about the number of ATS points that littlebird has right now....."666"......gotta be a conspiracy in that somewhere!
