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 ServicesNo Products but Services

“There are no products, only solutions”

• Not what customer wants but why they want

• A problem solving approach

• Simple Solutions

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 homee.g.

– My yahoo, Google Homepage, myspace– Firefox extensions

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

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

• RSS

Harnessing Collective Harnessing Collective IntelligenceIntelligence

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

Harnessing Collective Harnessing Collective IntelligenceIntelligence

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

Harnessing Collective Harnessing Collective IntelligenceIntelligence

• 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 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”

End of the Software Release End of the Software Release CycleCycle

• “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 Software above the level of a Single DeviceDevice

• 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 2.0Benefits of Web 2.0Reduced 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 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• Youtube search: The Machine is Us
