Web's evolution - Part 1

    The Web 2.0 term was proposed by Tim O’Reilly in conference brainstorming session between O'Reilly and MediaLive International, in which he envisioned several competencies. With the new versioning the old fashioned Web, as we know it, became Web 1.0, while in the literature were mentioned other two versions - Web 3.0 for the Semantic Web and Web 4.0 for the Noosphere. There are many people who are not comfortable with the version addressing of the Web, on one side it doesn’t seem natural, while on the other side it’s the easiest manner to encompass the set of characteristics or philosophies in the smallest unit of meaning.

    The transition between the different versions is occasionally marked with vague comparisons in which are reflected two or three characteristics, some of them are fixed, while other dependent on authors’ expectations. Into the below table I tried to put together some of the characteristics of what each Web version is about, there are still blank spaces, there are even wild guesses about what the future might bring. The table is not perfect, but it summarizes somehow my understanding about Web’s expectations.
