The Difference of Web 1.0, Web 2.0, Web 3.0

Web 1.0  is a one-way communication. Web 1.0 was an early stage of the evolution of the World Wide Web, centered around a top-down approach to the use of the web and its user interface. The website's provider will be the only one who can update the content.

Web 2.0 is a two-way communication. There will be the interaction between the user and the user, or the website's provider and the user. The user will be able to comment or create the content. For example; the Blog, Forum, Facebook, and etc.

Web 3.0 is the evolved of web 2.0. It  is more optimized for the searching and the matching with the keywords of the user.
