      From Web 2.0 to Social 3.0, what is the main difference? In the journal, the author points the main difference is that software supports synchronous collaboration, but sites only support asynchronous collaboration in the Web 2.0. To put it simply, in the Web 2.0, we only can send a text; receive a reply; repeat in a sites. However, in Social 3.0, not only do we can do things that in the Web 2.0, but also we can engaged doing something inside an app or in a Web page. It is a big deal in the information era.

     Social 3.0 also make a contribution to our study. In Web 2.0, I only can send a text about my thoughts in the sites. Sometimes, it is difficult for others to know my real meanings, and they often misunderstand what I want to do. However, with the help of Social 3.0, I can take part in the synchronous collaboration. For example, we make group presentation PPT in Prezi.com. In this site, we can do it together and clearly, as well as we can save time, because we need not do it one by one. Therefore, Social 3.0 shows a new step in the information era.
