Early web pages were static, much like book content – "read only" mode ... Interactive elements soon crept in such as bulletin boards and data-submission forms. Around 2004, users began taking the driver's seat, actively altering content and debating points with other readers. The jargon for this movement is "web 2.0," as if the Internet were a software program in its second release. Other terms you'll hear bandied about include "participatory web" and "architecture of participation".
Insider talk aside, it boils down to this: with the most basic computer skills, cybersurfers can tinker with some web pages. Examples of this trend include:
- Collective intelligence sites like Wikipedia. A "wiki" allows many users to edit and add content, pooling intelligence.
- Social networking sites like Facebook and Twitter that encourage group communication through microblogging, link-sharing and threaded discussions.
- User-generated-content sites like TripAdvisor and parts of Amazon.com that rely on free reviews from users. Also called "crowd-sourced" ... most often by downsized journalists.
We'll discuss the evolution of Web 2.0 sites further throughout the term, as well as the heralded rise of Web 3.0, the semantic web (sites capable of something more closely resembling human thought. For example, in the future, Wikipedia might be able to answer a question, rather than supplying a variety of links, based on keywords).
