“The evolution from an interactive Internet (often called Web 2.0) toward a more intelligent, semantic web will not happen as a result of dramatic new inventions or jointly agreed standards, but through a gradual evolution and recombination of existing technologies. To get to a Web 3.0, we will need to first create (and maybe be satisfied with) a Web 2.5, and that will happen through the gradual evolution of effective, user-based interaction protocols (based on user dialogues) and the use of queries as information passing mechanisms.” (Espen Andersen ~ Ubiquity November 2010 issue)
