3. Web 1.0 was Commerce
Web 2.0 is People
- Ross Mayfield
Web 2.0 seems to be like Pink Floyd
lyrics: It can mean different things to
different people, depending upon the
your state of mind.
- Kevin Maney

4. IntroductionIntroduction
• The concept of "Web 2.0" began with a
conference brainstorming session between
O'Reilly and MediaLive International in 2004
• The phrase "Web 2.0" hints at an improved form
of the World Wide Web
• Emphasizing tools and platforms that enable the
user to Tag, Blog, Comment, Modify, Augment,
Rank, etc.
• The more explicit synonym of "Participatory
Web"

5. Principles of Web 2.0

6. No Products but ServicesNo Products but Services
“There are no products, only solutions”
• Not what customer wants but why they
want
• A problem solving approach
• Simple Solutions

7. CustomizationCustomization
• 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
e.g. (This slide is better for reading online)

8. Customization
• Every individual is unique
• Allow him to choose instead of forcing him to use what
you have made
• Some people want to be different
• Make him feel home
e.g.
• My yahoo, Google Homepage, myspace, my naukri??
• Firefox extensions
e.g (This slide is better for taking printouts).

9. Focus on the “Long Tail”Focus on the “Long Tail”
• Reach out to the entire web
• To the edges and not just to the centre, to
the long tail and not the just the head
• Leverage customer-self service
e.g. Google, StumbleUpon, orkut

10. Harnessing Collective IntelligenceHarnessing 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
– Cloudmark – Spam emails

11. Harnessing Collective Intelligence..Harnessing Collective Intelligence..
Some systems,designed to encourage
participation
–Pay for people to do it – ‘gimme five’
–Get volunteers to perform the same task
• Inspired by the open source community
–Mutual benefits e.g. P2P sharing

12. Harnessing Collective IntelligenceHarnessing Collective Intelligence
• But only a small percentage of users will go to
the trouble of adding value to your applications
via explicit means.
• Therefore web 2.0 companies set inclusive
defaults for aggregating user data and building
value as side effect of ordinary use of the
application.
• It requires radical experiment in trust
“with enough eyeballs, all bugs are shallow”
- Eric Raymond

13. Specialized DatabaseSpecialized Database
• Every significant application to date has
been backed by a specialized database
– E.g. Amazon, Google, Ebay
• Database management is the core
competency of Web 2.0 companies
• “infoware” rather than merely “software”

14. Who owns the dataWho owns the data
• Control over data has led to market control
and oversized financial returns
• It will provide a sustainable competitive
advantage to the company
• Especially is data sources are expensive
to create or amenable to increasing
returns via network effects
• Race is to own certain classes of core
data e.g. naukri.com, 99acre, yahoo

15. End of the Software Release CycleEnd of the Software Release Cycle
• “Release Early and Release Often”
• “Perpetual BETA”
• Daily operations must become a core
competency
• Software will cease to perform unless it is
maintained on a daily basis

16. End of the Software Release Cycle..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

17. Software above the level of a Single DeviceSoftware 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.

18. Benefits of Web 2.0Benefits of Web 2.0
Recruitment:
Due to the cutting-edge underlying technologies and
usability-focused interfaces (the ‘cool’ factor)
Organisations adopting Web 2.0 tend to attract
sophisticated, high-caliber technical candidates.
Reduced cost:
Not only are Web 2.0 offerings low-cost, but the same
techniques can also be applied to existing (non-Web 2.0)
products and services, lowering costs.
For example, wikis can enable your users to build
documentation and knowledge base systems, with
relatively little investment from yourself.

19. Loyalty
The open, participatory Web 2.0 environment
encourages user contribution, enhancing customer
loyalty and lifespan.
Marketing/PR.
By taking advantage of the aforementioned benefits,
marketing and PR teams can implement low-cost, wide-
coverage, viral strategies.
Search Engine Optimisation (SEO)
Web 2.0 delivery mechanisms - such as Blogs and RSS
- significantly enhance search engine exposure through
their distributed nature

20. Summing UpSumming 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

21. SoSo FarFar SoSo GoodGood
In the year and a half since, the term
"Web 2.0" has clearly taken hold, with
more than 9.5 million citations in Google.
2005 2006

22. What Next ??

23. Web 3.0Web 3.0
• This term that has been coined to describe
the Semantic Web
• It promises to “organize the world’s
information”
• Can reason about information and make
new conclusions
