What is Web 2.0 ?

We hear this everyday, everywhere. So what does really web 2.0 means?

Wikipedia defines it as:

Web 2.0 is a term often applied to a perceived ongoing transition of the World Wide Web from a collection of websites to a full-fledged computing platform serving web applications to end users. Ultimately Web 2.0 services are expected to replace desktop computing applications for many purposes.

The concept of “Web 2.0″ began with a conference session between O’Reilly and MediaLive International. To a general user, web 2.0 is a highly interactive, very attractive, user friendly web application. In the initial period of Web 2.0 it was defined with the help of following example.

Web 1.0	Web 2.0
DoubleClick	Google AdSense
Ofoto	Flickr
Akamai	BitTorrent
Mp3.com	Napster
Britannica Online	Wikipedia
Personal websites	Blogging
Evite	Upcoming.org and EVDB
Domain name speculation	Search engine optimization
Page views	Cost per click
Screen scraping	Web services
Publishing	Participation
Content management systems	Wikis
Directories (taxonomy)	Tagging (“folksonomy”)
Stickiness	Syndication

In todays date web 2.0 means much more than that. Web 2.0 has changed the way websites are designed, most of the web 2.0 websites are completely built on css and they host some really crispy, shiny vector images.
