Billing the event as “Naked Networking,” the organizers of Expo Tech Expo obviously have fun on the job. And why not? This online 3D exposition for exposition technology is a first for the industry and definitely unusual. Virtual attendees with high-speed Internet access and a little time to learn the system will actually be able to walk down the online halls as an avatar. An attendee avatar will be able to talk to an exhibitor avatar. Is that fun, or what?
