4. Web 2.0 : Its hard to Define
“Web 2.0” a phrase coined by O'Reilly in 2003
and popularized by the first Web 2.0 conference in 2004
Web 2.0 is the network as platform, spanning all connected devices; Web 2.0
applications are those that make the most of the intrinsic advantages of that platform:
delivering software as a continually-updated service that gets better the more people use
it, consuming and remixing data from multiple sources, including individual users, while
providing their own data and services in a form that allows remixing by others, creating
network effects through an quot;architecture of participation,quot; and going beyond the page
metaphor of Web 1.0 to deliver rich user experiences.

● Not just technology
● What makes Web 2.0particularly interesting is that it’s a culture.

● Trying to implement Web 2.0 technology without embracing the
culture is a great way to mark yourself as a “clueless suit”
● Web 2.0 is largely driven by hobbyists.
