9. History
• Berners-Lee envisioned a read/write web
• we weren’t ready in the 1990’s for such a big
step
• we started with a read-only web – a place
where everyone could read whatever they
wanted, but only a select few(programmers)
could write web pages.
• This was web 1.0
10. • The concept of "Web 2.0" began with a
conference brainstorming session between
O'Reilly and MediaLive International in 2004
• Emphasizing tools and platforms that enable the
user to Tag, Blog, Comment, Modify, Augment,
Rank, etc.
• The more explicit synonym of "Participatory
Web” or “Read/Write web”
Introduction

12. Web 2.0 services and tools:
• Social networks (facebook, orkut, myspace, friendster)
• Web-based applications (Google docs, TimeTracker)
• Wikis (wikipaedia)
• Blogs, photologs or podcasts (blogger, Wordpress)
• Social bookmarking (digg, del.icio.us)
• Communication tools (basecamp, zoho project, meebo)
• Subscription systems (bloglines)
• Searchers based on tags (flickr, technorati)
• ...
13. Web 2.0 basic characteristics:
• Application used entirely through a web
browser (access info)
• Users own the data on the site and exercise
control (manage info)
• Users are encouraged to add value (create
info)
• Some Social-Networking aspects are included
(participate)
• A rich, interactive, user friendly interface (easy
to use)
14. Web-as-information-source Vs Web-as-participation-
platform
(access info)
(access info)
(create info)
(promote info)
(manage info)
Access to info (generated by institutions or other users)
Add new content (e.g. knowledge, opinion or experience)
Share your things (e.g. photos, writings)
Control the info (delete, promote, correct or complete)
Suming up (vote the best places to travel or interesting blogs)
Put your things online (tasks, meetings, gift lists or a list of
books)
Now, You are the participant
15. Blogs: user’s voice on the web
A blog is a website where entries are made in journal style and
displayed in a reverse chronological order

knowledge)
• Blogs can allow for comments from readers
• Primarily textual, but no restrictions (photos, video, audio, etc.)
• Blogs are for communication!

There are at least 70
millions, and growing
(2x each 6 months!)
16. Wikis
• Wiki is the Hawaiian word for “quick”

“Six Degrees of Separation”
18. RSS Feeds
• Really Simple Syndication, Rich Site Summary
• Originally used to syndicate content from another website on
your own
• Now most commonly used to deliver web related updates
• Makes it easy to keep up with content from news sites, blogs,
wikis, and other websites without visiting them every day
• To read RSS Feeds you need an RSS Aggregator
• RSS Aggregators are like inboxes for your RSS feeds
• With only one RSS Aggregator you can read new
content from hundreds of web sites
19. Tagging ,Tag Cloud, Folksonomies & Social
Bookmarking
• By ‘tagging’ articles, pages, blog posts, etc., the lay person
can easily organize data in terms they understand
• Folksonomy - collaborative tagging, social
classification, social indexing, and social tagging
• Folksonomy = folk + taxonomy , hence a folksonomy is a
user generated taxonomy = user defined labels/tags to
organize information

24. The Internet Economy…
The Long Tail Effect Freemium Business
Model
• Amazon.com , Netflix.com
• Significant profit – out of
selling small volumes of hard-
to-find items to many
customers, instead of only
selling large volumes of a
reduced number of popular
items
• Offer basic services for
free
• Charge a premium for
advanced or special
features
• 37 Signals – a success
story
• SEO = Search Engine Optimization
• PPC = Pay Per Click
• Affiliation
The Internet Marketing
Market
25. Technology matters…
• AJAX = Asynchronous Javascript And XML
• XML = Extensible Markup Language
• RDF = Resource Description Framework
• REST = Representational State Transfer
• SOAP = Simple Object Access Protocol
• XHTML = Extensible HTML
• SVG = Scalable Vector Graphics
27. • A range of web based software programs
• Software allows user to interact and share data with
others
• Open APIs, service oriented design
• Collaborative Software
Social Software?
28. • Services, not packaged software, with cost-effective
scalability
• Control over unique, hard-to-recreate data sources
that get richer as more people use them
• Trusting users as co-developers
• Harnessing collective intelligence
• Leveraging the long tail through customer self-service
• Software above the level of a single device
• Lightweight user interfaces, development models,
and business models
Some Principles…
29. No Products but Services
“There are no products, only solutions”
• Not what customer wants but why they want
• A problem solving approach
• Simple Solutions
30. Customization/Personalization
• Every individual is unique
• Some people want to be different
• Allow him to choose instead of forcing him to
use what you have made
• Make him feel home
e.g.
• My yahoo, Google Homepage, myspace
• Firefox extensions
31. Harnessing Collective Intelligence
Network effects from user contribution are the key
to market dominance in Web 2.0 era
The Wisdom of crowds – Users add value
• Amazon, ebay - User reviews, similar items, most popular
• Wikipedia – content can be added/edited by any web user
• Flickr – tagging images
32. Harnessing Collective Intelligence..
Some systems,designed to encourage
participation
• Pay for people to do it
• Get volunteers to perform the same task
o Inspired by the open source community
• Mutual benefits e.g. P2P sharing
33. Specialized Database
• Every significant application to date has
been backed by a specialized database
o E.g. Amazon, Google, Ebay
• Database management is the core
competency of Web 2.0 companies
• “infoware” rather than merely “software”
34. End of the Software Release
Cycle
• “Release Early and Release Often”
• Perpetual BETA = software which never leaves
the development stage of beta
• Daily operations must become a core
competency
• Software will cease to perform unless it is
maintained on a daily basis
35. End of the Software Release Cycle..
• Automate the maintenance process
• Real time monitoring of user behavior
• Microsoft – upgrades every 2-3 yr
• Flickr- Deploy new build up to every half hr
“Put two or three new features on some part of the site
everyday, and if user don’t adopt them, take them out. If
they like them roll them out on entire site” - Anonymous
36. Software above the level of a Single
Device
• The PC is no longer the only access device
for internet applications
• Applications that are limited to a single device
are less valuable than those that are
connected.
• Design your application from the get-go to
integrate services across handheld devices,
PCs, and internet servers.
37. Summing Up
• No products but solutions
• Customization ability
• Focus on long tail
• Users add value
• Specialized Database
• Perpetual Beta
• Software above the level of single device
38. Why Web 2.0 ?
• Cognitive Surplus
• Participation
• Personalization
• People Oriented
39.
40. Web 3.0
• This term has been coined to describe the
Semantic Web
• It promises to “organize the world’s
information”
• Can reason about information and make
new conclusions
