- 11. 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
- 12. No Products but Services “ There are no products, only solutions” Not what customer wants but why they want A problem solving approach Simple Solutions
- 13. 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 )

- 15. 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
- 16. 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
- 18. 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
- 19. Harnessing 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
- 20. 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”
- 21. 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
- 22. 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.
- 23. 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
- 24. 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 Youtube search: The Machine is Us
