Interactive web services and applications that give users free choice to interact or collaborate with each other -the term web 2.0 is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design,[1] and collaboration on the world wide web. a web 2.0 site gives its users the free choice to interact or collaborate with each other in a social media dialogue as creators (prosumer) of user-generated content in a virtual community, in contrast to websites where users (consumer) are limited to the passive viewing of content that was created for them. examples of web 2.0 include social-networking sites, blogs, wikis, video-sharing sites, hosted services, web applications, mashups and folksonomies.
