The Web 2.0
The first sign that something was changing on the Web was the underground popularity of a site called LiveJournal and the very visible surge of interest in a site called Friendster. These sites, which came to be called "social networking sites," were rapidly emulated by such services as Tribe, LinkedIn, Google's Orkut, Flickr, and Yahoo 360. Writers conversant with the works of social network analysts, people like Duncan J. Watts and Mark Buchanan, for example, noticed that similar patterns existed in these online networks. Something was happening here.

What was happening was that major parts of the World Wide Web were acquiring the properties of communications networks, the sorts of networks found to exist (albeit on a much smaller scale) in the physical world. And that the Web itself was being transformed from what was called "the Read Web" to the "Read-Write Web," in accordance with Tim Berners-Lee's original vision. Proponents of this new, evolving Web began calling it Web 2.0 and in short order the trend became a movement.

"Enter Web 2.0, a vision of the Web in which information is broken up into "microcontent" units that can be distributed over dozens of domains. The Web of documents has morphed into a Web of data. We are no longer just looking to the same old sources for information. Now we're looking to a new set of tools to aggregate and remix microcontent in new and useful ways".

In a nutshell, what was happening was that the Web was shifting from being a medium, in which information was transmitted and consumed, into being a platform, in which content was created, shared, remixed, repurposed, and passed along. And what people were doing with the Web was not merely reading books, listening to the radio or watching TV, but having a conversation, with a vocabulary consisting not just of words but of images, video, multimedia and whatever they could get their hands on. And this became, and looked like, and behaved like, a network.

Nowhere is this clearer than in the world of blogging. In a few short years the blog went from a few idiosyncratic Web sites to something used by millions of people empowered by content creation tools such as Blogger and Wordpress. Even more importantly, these blogs were connected to each other through the mechanism of RSS, a simple XML format that allows bloggers to send their content to a network of readers (called 'subscribers').

But it wasn't just blogging. Creating an online community became a snap with tools such as Plone and Drupal. Moreover, using a collaborative writing tool called the wiki Jimmy Wales and a few thousand of his friends created a site called Wikipedia, rendering Encyclopedia Britannica obsolete in the process. Others, using the free audio-recording tool Audacity, began recording their own talk and music; this, when combined with RSS, became podcasting, a rapidly rising phenomena that is transforming what we think about radio.

For all this technology, what is important to recognize is that the emergence of the Web 2.0 is not a technological revolution, it is a social revolution. "Here's my take on it: Web 2.0 is an attitude not a technology. It's about enabling and encouraging participation through open applications and services. By open I mean technically open with appropriate APIs but also, more importantly, socially open, with rights granted to use the content in new and exciting contexts".
