What is WEB 2.0 ?
Basically, the term encapsulates the idea of the proliferation of interconnectivity and social interactions on the Web.

Tim O'Reilly regards Web 2.0 as business[3] O'Reilly considers that Eric Schmidt 's abridged slogan, don't fight the Internet, encompasses the essence of Web 2.0 — building applications and services around the unique features of the Internet , as opposed to building applications and expecting the Internet to suit as a platform (effectively "fighting the Internet").

The term Web 1.0 came into use after the evolution of the term Web 2.0. embracing the web as a platform and using its strengths (global audiences, for example).

Problems with WEB 1.0.......
In the opening talk of the first Web 2.0 conference , O'Reilly and John Battelle summarized what they saw as the themes of Web 2.0.

Advantages of WEB 2.0.........
According to O'Reilly and Battelle,an architecture of participation where users can contribute website content creates network effects . Web 2.0 technologies tend to foster innovation in the assembly of systems and sites composed by pulling together features from distributed, independent developers.

This could be seen as a kind of "open source" or possible "Agile" development process, consistent with an end to the traditional software adoption cycle, typified by the so-called " perpetual beta ".

[33] On the basis of this application, CMP Media sent a cease-and-desistIrish non-profit organization [email_address] on May 24 , 2006 , [34] but retracted it two days later. [35] The "WEB 2.0" service mark registration passed final PTO Examining Attorney review on May 10 , 2006 , but as of June 12 , 2006 the PTO had not published the mark for opposition.

Criticism for WEB 2.0.....
>> The argument exists 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.
>>Techniques such as AJAX do not replace underlying protocols like HTTP , but add an additional layer of abstraction on top of them (more or less the same way as C++ language is an abstract layer on top of C language.
>>Many of the ideas of Web 2.0 had already been featured in implementations on networked systems well before the term "Web 2.0" emerged.
>> Venture capitalist Josh Kopelman noted that Web 2.0 had excited only 530,651 people (the number of subscribers at that time to TechCrunch , a Weblog covering Web 2.0 matters), too few users to make them an economically viable target for consumer applications.
