11. 6.CRITICISM:

"Web 2.0" does not represent a new version of the World Wide Web at all.
Its an advanced version of Web 1.0.

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 well before the term "Web 2.0"
emerged.Eg: Amazon.com
