Former Linden Lab CTO Cory Ondrejka just blogged some of this thoughts on where virtual worlds are going over the next 5 to 10 years, and they are worth reading.
* His slide presentation from his final lecture
* Some notes he blogged while working on that deck
PS. I really like Cory’s 150+ slide deck machine gun of images and blurbs approach to presenting (when I first saw the typical number of slides he used, I was, ah, a little taken aback!)
