I've been looking at various vendor solutions (Mentorware and ZiffDavis) that provide that "Virtual Tradeshow". It's always pretty expensive and too new to be fully understood. I, personally thought that these solutions just duplicate what can be done in Second Life... but Second Life has its sets of limitations, like not being able to gather attendee's info, business needs to generate good Leads for our sales force.
It's also pretty cool if we can showcase our exciting tools and technologies online, while having a place for mavens to participate and collaborate to such an event.
Came across an interesting article about it, which stirred up this whole topic again... and you know what? this article says "know your audience" and "content is king"... funny how everything we do online revolves around that formula ;-)
Question to our audience: would you want Sun to have a Virtual Tradeshow??
