Web 3.0 is the Web enabled mobile device. I think all of those estimates about the amount of content that will be created on the Web are grossly understated. - Tac Anderson

dude, I think Web 3.0 is web connected everything. Tv, mobile, radio, billboards and these devices know who/where you are. A good example are location based services like Loopt, brightkite. They are posed to blow up when the Iphone 3g and gps enabled android phones start becoming min stream. Imagine these devices being able to talk to your TV, telling it where you have been, what ads you looked at, etc, then while you are watching streaming video, the television shows you ads based on thesse activities. - Joe Mac Stevens
