Some Critisism <ul>Some Critics of the term claim that "Web 2.0" does not represent a new version of the World Wide Web at all, but merely continues to use so-called "Web 1.0" technologies and concepts. For example <li>Techniques such as AJAX do not replace underlying protocols like HTTP, but add an additional layer of abstraction on top of them.
Many of the ideas of Web 2.0 had already been featured in implementations on networked systems </li></ul>
<ul>well before the term "Web 2.0" emerged <li>Amazon.com, for instance, has allowed users to write reviews and consumer guides since its launch in 1995, in a form of self-publishing
But perhaps the most common criticism is that the term is unclear or simply a buzzword.
"Nobody really knows what it means...If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along." </li></ul>
