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?
