Web 2.0: An Overview

Web 2.0 - Origin
Web 2.0, a phrase coined by O'Reilly Media in 2003, refers to a perceived second generation of web-based communities and hosted services – such as social-networking sites, wikis and folksonomies – that facilitate collaboration and sharing between users.

The Evolving Web
Technologies such as weblogs, social bookmarking, wikis, podcasts, RSS feeds (and other forms of many-to-many publishing), social software, Web APIs, Web standards and online Web services imply a significant change in web usage.

Web 2.0 refers to:
The transition of web sites from isolated information silos to sources of content and functionality, thus becoming computing platforms serving web applications to end-users
A social phenomenon embracing an approach to generating and distributing Web content itself, characterized by open communication, decentralization of authority, freedom to share and re-use.

Openness
In the end, the bottom line boils down to one concept: openness. Openness in business practices. Openness in classrooms. Openness in software and applications. The more we share, the more we benefit. Give away some power, some information and get so much more back.

Harnessing Collective Intelligence Information must flow freely Information must be processed in some way -
else it remains a collection of opinions and not knowledge
A ‘wise’ crowd:– Diversity of opinion– Independence: People’s opinions aren’t
determined by the opinions of those around them. – Decentralization: People are able to specialize and
draw on local knowledge. – Aggregation: Some mechanism exists for turning
private judgments into a collective decision.

Concise Web 2.0 Explanation
http://web2journal.com/read/165914.htm
“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 “architecture of participation,” and going beyond the page metaphor of Web 1.0 to deliver rich user experiences.”
