i attend tradeshows for other industries annually and always come away with so much more insight than what i've learned the rest of the year by simply speaking to reps on the phone, reading literature, etc.
i was envisioning inviting some of the internet video oriented company reps, venture capitalists, domainers, etc to come together for a 1 or 2 day session with a planned agenda.
i'm a believer in pooling resources for more efficient information harvesting. face-to-face encounters bring on some of the most brilliant tangents.
