What do you think Web 2.0 is?

Paradigm shifts

Paradigm shifts

Web 2.0 definitionNo definitive definition (still evolving) Moves the focus to the user of the information, not the creator of the information Information moves “beyond” web sites Information has properties and these properties

follow each other and find relationships Information comes to users as they move around Information is broken up into ‘microcontent’ units that can be distributed over

many domains Interaction is no longer limited to (X)HTML Users are able to control how information is categorized and manipulated User interface becomes a ‘fat’ rather than ‘thin’ client Requires a new set of tools to remix microcontent in new and useful ways

Another Web 2.0 definition

Web 2.0 is a convergence of individual traits, and social and technological forces

User-Focused Web = User Satisfaction Natural result of Web evolution - focus on user

generated content creation and management

Web 2.0 drivers

The “dot-com” collapse forced a web re-examination

Web reached a critical mass – (Good) information content sources

– Use (and desire for reuse)

– Trust

Web users developed an expectation

of fulfillment

Web 2.0 facilitators

Computing power – Still doubling every 18 months (if not less??) – PC-based data centers (cloud computing)

Connectivity – Low cost, broadband Internet – Wireless, broadband access

Web 2.0 facilitators

Device proliferation – PDAs, cell phones, etc

Internet standards – XML-based integration

User Interfaces – many possibilities

Web 2.0 examples

Folksonomy; Internet-based information retrieval methodology consisting of collaboratively generated, open-ended labels that categorize content such as Web pages, online photographs, and Web links.

What Web 2.0 is not

Semantic Web (addition of machine-readable descriptions to content to add meaning facilitating automated information gathering and research by computers)

A new collection of technologies Blogging, wikis (user enabled web editing),

and RSS (Really Simple Syndication) feeds – these are simple web features

Collective intelligence

Key Element of Web 2.0 –Collective Intelligence

An architecture of participation Users add value An evolved Web perspective User ratings User tagging

Web 2.0: Rich user experience

Goal of Web 2.0 - A Rich User Experience

Get the user to content they want Link the user to content they might want Don’t tell the user how to find content Let the user decide how to use the content Do all of the above quickly and efficiently

Web 2.0 Overview Transition of websites from isolated information silos to sources of

content and functionality, becoming computing platforms serving web applications to end users

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, and "the market as a conversation"

More organized and categorized content, with a far more developed deep linking web architecture than before

Shift in economic value of the Web, possibly surpassing that of the dot com boom of the late 1990s

Has lead to a resurgence of excitement around the implications of innovative web-applications and services

Effectively you provide the content!
