Introduction Web 2.0 technologies are basically related to web technologies through which web pages are designed and developed. The main focus of these web pages is interactive information sharing among users, user centered design of the page that can be modified and edited by the user and whatever changes are made to the web page by the users, they are totally compatible with the web. Example of these Web 2.0 web sites are listed as follows, however it should be kept in mind that the following examples are categories not the actual websites:  1. Hosted Services  2. Social Networking sites  3. Web applications  4. Vide sharing sites  5. Virtual Encyclopedias  6. Public Blogs  7. Folksonomies Latest Trends On a general note, the year 2007 was one of the most important years in the development of web sites that used the Web 2.0 technology as many developers believe that 2007 was the year when the technology actually realized its true potential and web pages were put into the phase of transition from simple Web 1.0 technology to Web 2.0. In 2007, not only did new Web 2.0 web pages and sites were seen in the stage, but, major investors like Microsoft and Google also started to acquire some of those as they realized the potential that these websites would have in order to help them achieve their goals. It was anticipated in 2007 that more and more people could be connected to each other through this technology and they can be made habitual to using these forums. Once the users make these services a part of their lives, then these major companies can also present their own messages, presence and their products while the users do their own work. This is one of the easiest way to market products and services to especially the students who are more indulged in using services like this and are the target markets of most of the companies. Not only are these platforms cheaper to advertise then the normal media, but they are catering to a much larger chunk of population at the same time as compared to other forms of media. Also, by making things more and more interactive and giving the entertainment into the hands of the users, attracting and retaining users on these websites has become much easier (Fox 2007). According to a survey, besides the rest of the world, only India saw around 150 such startups that used the Web 2.0 technology and gave users an experience with the web that they have not experienced before. Also, it is after the introduction of these websites and applications that internet has now become the part of our lives.
