Wait…Wait…

If there’s a Web 2.0…If there’s a Web 2.0…

What’s Web 1.0?What’s Web 1.0?

Who? The usual suspects

Computer industries Information industries

Those who use/are interested in Human activities,

events Human creations Human institutions

Let’s break it down…

Key concepts: Individual production & user-generated content Harnessing the power of the crowd Data on an epic scale Architecture of participation Network effects Openness

-- Dr. Linda Main, SJSU-SLIS, LIBR 246-15 class, Fall 2007

Let’s break it down…

In sum, Web 2.0 is online… …collaboration …contribution …community

Focus is on the user Read-and-Write Web – Web as Platform

Individual Production & User-Generated Content

Rising model of information production-dissemination-consumption cycle 2-way / multi-way conversation2-way / multi-way conversation Questions who has authority to say, to knowQuestions who has authority to say, to know Experts vs. AmateursExperts vs. Amateurs

Individual Production & User-Generated Content

Some toolsSome tools BloggerBlogger RSS feeds, readersRSS feeds, readers YouTubeYouTube FlickrFlickr DeliciousDelicious

Individual Production & User-Generated Content

Some definitions Blog

Web log or diary; a web page organized chronologically

Characteristics: chronological organization, easy to set up, update

Describes format, not content Exs: Armacost Library, TechDirt, Chronicle of

Higher Education

Individual Production & User-Generated Content

Some definitions RSS

Really Simple Syndication Standardized feed format

Allows form and content to be separated Based on XML

Allows for easy dissemination of frequently updated Web documents

Users can subscribe to a page, receive notifications of updates

RSS Reader exs: Bloglines, Google Reader

Individual Production & User-Generated Content

Individual Production & User-Generated Content

Harnessing the Power of the Crowd

Crowdsourcing, collective intelligence, the wisdom of the crowd

Depends on collaboration – the social aspect of the web

Questions authorship, ownership, intellectual property rights

Harnessing the Power of the Crowd

The central principle behind the success of the giants born in the Web 1.0 era who have survived to lead the Web 2.0 era

appears to be this, that they have embraced the power of the web to harness

collective intelligence.

-- Tim O’Reilly, “What Is Web 2.0,” 09/30/2005

Harnessing the Power of the Crowd

Wikipedia – prime example Wiki

A web site/page that can be easily edited by anyone who is allowed access

‘wiki’ – Hawaiian for ‘fast’

Harnessing the Power of the Crowd

Harnessing the Power of the Crowd

Social bookmarking Users choose terms to associate Web

pages/sites Users organize information themselves

Activity: ‘tagging’ Result: ‘folksonomies’ Ex: Delicious

Harnessing the Power of the Crowd

Twitter Social networking, micro-blogging service Users send, read updates or ‘tweets’ Ex: Play Machinima Law Conference @

Stanford Law School CIS, April 24-25, 2009 http://cyberlaw.stanford.edu/ http://search.twitter.com/search?q=%23pml

Data on an Epic Scale

Explosion of Information Acceleration & Increase

Production Dissemination Distribution

Affects new and old media Challenges established assumptions of order

Architecture of Participation

Design encourages participation, contribution, lowers barriers

Based on ‘open’ principle Opens up production to all users Exposes data for reuse and recombination,

‘mash-up’

Questions ownership, intellectual property rights

Architecture of Participation

Design implies continuous improvement perpetual ‘beta’ perpetual ‘beta’

Design ramps up ‘Web as Platform’Design ramps up ‘Web as Platform’ Questions perfectionism, established rules

of order, software release life cycle

Network Effects

More participation better tool, service better tool, service Wikipedia entry for network effectWikipedia entry for network effect Critical mass must first be achieved Ex: Wikipedia

Network Effects

Power Laws & The Long Tail Power Law – mathematical concept,

frequency distribution “80/20 Rule” Power law distribution graphs tend to have

long tails

Network Effects

Power Laws & The Long Tail The Long Tail – business strategy coined

by Chris Anderson, Oct 2004 remove physical barriers, demand for niche

products are actually high Ex: Amazon.com

Network Effects

We are moving towards a culture and economy in which the huge numbers of people who do (or can) participate in the

niches of the Long Tail really matter.

-- Dr. Linda Main, LIBR 246-15,SJSU-SLIS Fall 2007

Openness

Open source Open access Open API (Application Programming Interface) Exposes data Free to use, access and remix

Services Data

Questions ownership, intellectual property rights

Openness

Also an attitude or outlook… Trust Play

Let’s recap…

Let’s recap…

We shape our tools

and thereafter our tools shape us.

-- Marshall McLuhan, 1964, Understanding Media: The Extensions of Man

So what?

So what?

It’s here, it’s now What’s next?

Mobile services, SMS technology What will happen to familiar formats, processes,

institutions?

So what?

It’s changing things But what is it again?

Is this a publishing revolution?

To what extent? Is it a revolution at all?

So what?

‘Teaching the Machine’ The semantic Web

Depends on us ‘The Machine is Us/ing Us’

Presents us with challenges, opportunities Will we rise to meet them?
