EOI Web 20

Mariano Aguirre Paredes

A short introduction

Internet is a global system of interconnected computer networks that interchange data .

Created by the USA Air Force ARPANET October 29, 1969

Internet <> World Wide Web

As of June 30, 2008, 1.463 billion people use the Internet according to Internet World Stats

Web 1.0 was Commerce Web 2.0 is People - Ross Mayfield http :// ross.typepad.com / 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 http :// www.kevinmaney.com /

The origins

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

Emphasize tools and platforms that enable the user to Tag, Blog, Comment, Modify, Augment, Rank, etc.

The more explicit synonym of "Participatory Web"

Principles of Web 2.0 "For corporate people, the Web is a platform for business. For marketers, the Web is a platform for communications. For journalists, the Web is a platform for new media. For geeks, the Web is a platform for software development. And so on." Richard MacManus

No Products but Services

“ There are no products, only solutions”

Not what customer wants but why they want

A problem solving approach

Simple Solutions

Customization

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 )

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) .

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

RSS

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 (eoi, pug, rock climbing…)

Rockola.fm – tagging songs

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

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

Specialized 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”

End of the Software Release Cycle

“ Release Early and Release Often”

“ Perpetual BETA”

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

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.

Benefits of Web 2.0

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.

Quality controls are increasing:

The Ikea case

Kryptonite unbreakable locks

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
