The document discusses the key concepts of Web 2.0. It began as a conference in 2004 to discuss an improved form of the World Wide Web that emphasizes tools and platforms allowing users to tag, blog, comment on and modify content. Examples provided include services like My Yahoo, Google, and Flickr that allow high levels of customization and focus on the long tail of the market. The document outlines several principles of Web 2.0 applications including allowing user added value, utilizing specialized databases, adopting a model of perpetual beta to encourage constant improvement, and designing applications that can work across devices rather than single devices.

3. • 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"
• Focus on efficient and humane information flow

4. “There are no products, only solutions”
• Not what customer wants but why they
want
• Need orientation rather than product
• A problem solving approach
• Active participation of people and
networks
• Simple Solutions

5. • Every individual is unique.
• Some people want to be different
• Allow them to choose instead of forcing them to
use what you have made
• The less they are forced the more they will be
Interested
• Make them feel home
e.g.
• My yahoo, iGoogle, Myspace , Flikr ,Twitter.
• Firefox add-ons .

6. • Redefining search by intelligent networks.
• Cloud computing
• Warez legalization by advertisements
• P2P sharing over special servers
• Free for all data banks like Wikipedia
• Specific forums for specific uses
e.g. torrents, rapidshare, megaupload,

7. • Merging social networking and buisness
• Use of micro bloggers
• Advertisement according to consumer
preference
• Use of public forums for specific ads.
e.g. facebook, twitter, BlogSpot, Google Ad
Sense.

8. Network effects from user contribution are the key to
market dominance in Web 2.0 era
The Wisdom of crowds – User add value
• Amazon, ebay - User reviews, similar items, most popular
• Blogger – useful and most viewed blogs get paid
• Wikipedia – content can be added/edited by any web user
• Flickr – tagging images
• Firefox – users make specific addons
• Cloudmark – Spam emails

9. Some systems, designed to encourage
participation
• Pay people to do it
• Discussions over social networks
• Get volunteers to perform the same task
o Inspired by the open source community
• Mutual benefits e.g. P2P sharing
- Many companies maintain their facebook
pages

10. • But only a small percentage of users will go to
the trouble of adding value to your applications
via explicit means.
• So web 2.0 companies set aggregating user data
and building value as side effect of ordinary use
of the application.
• It requires radical experiment in trust and totally
new business models.
• Also creates a need for radical changes over
prevailing business polices

11. • Every significant application to date has
been backed by a specialized databases
o E.g. Amazon, Google, Ebay , IMDB.
• Database management is the core
competency of Web 2.0 companies
• Cloud computing decreases need for
large databases
• “infoware” rather than merely “software”

12. • Control over data has led to market control and
oversized financial returns.
• It will provide a sustainable competitive
advantage to the company.
• Personal data over social networking sites must
be protected.
• Especially if 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, Microsoft skydrive,
IMDB.

13. • “Release Early and Release Often”
• Perpetual BETA >>testing phase
• Daily operations must become a core
competency
• Constant feedback for improved products
• Software will cease to perform unless it is
maintained on a daily basis

14. • Automate the maintenance and update
process
• Real time monitoring of user behavior
• Microsoft – upgrades every 2-3 days
• Flickr- Deploy new build up to every half hour
“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

15. • The PC is no longer the only access device for
internet applications, handheld devices redefine
the information age
• New communication techniques also facilitate this
phenomena
• 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.
• Various open source freeware take a major share
of the market.

16. Recruitment:
Due to the cutting-edge underlying technologies and
usability-focused interfaces (the ‘cool’ factor)
Organizations 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.
e.g. wikis can enable your users to build documentation
and knowledge base systems, with relatively little
investment from yourself.

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

18. 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.
2006 2008

19. • No products but solutions
• Customization
• Focus on long tail
• User added value
• Specialized Databases
• Perpetual Beta
• Newer business models
• Software above the level of single device
• Open source preference
• Constant cycle of correcting and improving
