However, there is also an interesting saying: the Web2.0 is nothing but means the Web is going from client/server model to peer-to-peer model, or in other words, from elite model to mass model. just like music goes from classic to pop, dance from stage to street, TV from star actress to Super Girls, books from literature to cartoons, etc, etc. more

Xie Wen, a veteran of the Internet, is more easy to understand: "in the Web 1.0 era, we are concerned with people, Web 2.0 stores, and Web 1.0 stores. The Web 2.0 community must be developed based on the Community form, but Web 2.0 is not necessarily the community ." He also gave the Web 2.0 company the conditions for success: "This company must have modern and standardized enterprise systems and game rules, clear and complete strategies, experienced and competent teams, more than $10 million in investment, 1000 people/year of manpower. investment and 3 years of growth.
