Comment: WEB2.0 returns to the virginity of WEB0.0

From the technical implementation point of view, WEB2.0 is an Internet information dissemination and service model characterized by user-generated content from netizens. WEB2.0 forms a striking contrast with the centralized dissemination model of traditional portals represented by Sina and Yahoo. From the current business model perspective, the most successful WEB2.0 services include Wikipedia, online Q&A platforms (Yahoo Answers, Baidu Zhidao), blogs, and video sharing.
