I wouldn't be surprised if the list of attendees is up. The economy is down and there are a lot of people grasping at straws and even more "beer money" webmasters who probably think attending this show is the secret to making the big $$$.
They pool their money, four of them share a room at Harrahs, they eat and drink for free and grab some "really cool" freebies at the show they can take back and show their friends.
