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, servicebetter 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?
