Web 2.0, refers to a supposed second

generation of Internet-based services

that emphasize online collaboration and

sharing among users.

Web 2.0 is the business revolution in

the computer industry caused

by the move to the Internet as

platform, and an attempt to

understand the rules for success on

that new platform.

– Tim O’Reilly

…[web2.0 is a] philosophy of mutually maximizing collective intelligence

and added value for each participant by formalized and dynamic

information sharing and creation

…[web2.0 is an] idea in people's heads rather than a reality it’s actually an

idea that the reciprocity between the user and the provider is what's

emphasized in other words, genuine interactivity… simply because

people can upload as well as download
