WEB2.0

The concept of "Web 2.0" began with a meeting and the brainstorming part of O'Reilly and MediaLive International. Dale Dougherty, the so-called Internet pioneer and vice president of O'Reilly, noticed that, unlike the so-called "crash", the Internet is more important than ever, and exciting new applications and websites are appearing with amazing regularity. More importantly, those companies that survived the Internet bubble seem to have some similarities. Then, will the bursting of the bubble of Internet companies mark a turning point of the Internet, so that the voice of "Web 2.0" is meaningful? We all agree with this view, so the Web 2.0 conference was born.

The bursting of the internet bubble in the autumn of 200/kloc-0 marked a turning point of the internet. Many people think that the Internet is over-hyped. In fact, the internet bubble and the subsequent stock market recession seem to be the common features of all technological revolutions. A great stock market recession usually indicates that booming technology has begun to occupy the center stage. The counterfeiters were expelled, and the truly successful stories showed their strength, and people began to understand what made one story different from another.

In the year and a half after that meeting, the word "Web 2.0" has been deeply rooted in people's hearts, and more than 9.5 million links can be searched from Google. However, the meanings of the two versions of eb 2.0 are quite different. Some people belittle Web 2.0 as a meaningless marketing slogan, while others interpret it as a new concept.

Web2.0 is one of the hot concepts on the Internet after 2003, but there is no strict definition of what Web2.0 is at present. Generally speaking, Web2.0 (also called Internet 2.0) is a general term for a new type of Internet application compared with Web 1.0. The main feature of Web 1.0 is that users get information through browsers, while Web2.0 pays more attention to user interaction. Users are both consumers (browsers) and producers of website content.
