Web 3.0 rules!!!!

This isn't my web 2.0 assignment post, its just a follow up thought: When the web first made it big commercially people thought it was the be all and end all of everything. Wow AOL! Compuserve! 28 baud modems! WOW! Then within about 10 years web 2.0 was coined as a (truly horrible and annoying) term. Everyone (I'm talking to you Time magazine, random pundit, authors of our text books, etc...) thought that web 2.0 was the be all and end all of everything. WOW myspace! Facebook! flikr! WOW! Well, what happens when web 3.0 (inevitably) comes out. What will it look (feel? taste? think?) like, what will it do (or enable us to do)? Any thoughts or ideas?
