3. “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. Chief among those rules is this:
build applications that harness network
effects to get better the more people use
them.”
(O‟Reilly, 2006)

service and to share them with other
users of the system.
