Jim McNiel, CEO, and Steve Repetti, CTO of Fifth Generation Systems, dropped by my table at the Web 2.0 Expo to show off a very cool Web site tool called Zude. It was the coolest thing I saw at the Expo. Problem is, it is too cool — when they tried to release a beta they saw far more traffic than they were expecting. So the launch has been delayed as they reengineer their service. In either case it’s interesting to see what they were attempting to do.
