Web 2.0 is the use of CPU (Collective Processing Unit) for knowledge (Wikipedia), for Rating (Dig) and for creative thinking (Prediction Markets). Web 2.0 is one step nearer to Web 3.0 (TBL's Semantic Web) which is the use of NAI (Networked AI). The convergence of Web 2.0+Web 3.0 = Web 4.0 . Web 4.0 will lead to Trans-reality (Augmented Reality (RFID) + Virtual Reality (Second Life). Trans-reality is the necessary condition for the apperance of Blog-jects (objects that blog to each other).
