The study deals with the possibility of information loss in Web 2.0 due to the interaction between the overload and the real information. Using Gottesman and Preskill method, this investigation has proposed a mechanism to calculate the amount of information transformation in Web 2.0. In this proposal, there are three different Hilbert spaces that belong to the degrees of freedom of outside, inside, and overload information of Web 2.0. The information transformation in Web 2.0 is described at two stages. At the first stage, it is shown that the internal stationary state of Web 2.0 can be represented by a maximally entangled two-mode squeezed state of inside and overload information. At the second stage, the state of Web 2.0. is described by a maximally entangled two-mode squeezed state of overload and outside information. The amount of information transformation can be obtained by projecting the state at the first stage on the state at the second stage. Evidently, this study concludes that the information is not lost in Web 2.0.
