You don’t need to apologize for calling it Web 3.0. Of course the Web does not upgrade in one go like a company switching to Vista. But there is a definite phase transition from current technologies. My personal Web 3.0 definition is “the combination of Web 2.0 mass collaboration with structured databases”.
