Q: What is web 2.0?
A: The term "Web 2.0" refers to a perceived second generation of web development and design, that aim to facilitate communication, secure information sharing, interoperability, and collaboration on the World Wide Web. (From Wikipedia)
I think that the existence of "web 2.0" is the result of widespread use of computer. It gives the platform for everyone to not only surf but also interact with others on the Internet. I believe that the information on the Internet may become diversified by web 2.0. However, there is a point that I doubt. Because everyone has the right to post or edit their articles on the website such as wiki or blog, there may lead to some problems of property rights. How to prevent such problems from happening? It is a tough work.
