The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn. - Alvin Toffler Web 2.0 refers to second-generation internet-based services that emphasize online collaboration and sharing among users and encourage users to add value through tagging, commenting, and modifying content. Some key characteristics include rich, interactive interfaces; user-generated content; and network effects from user contributions.

- 9. History • Berners-Lee envisioned a read/write web • we weren’t ready in the 1990’s for such a big step • we started with a read-only web – a place where everyone could read whatever they wanted, but only a select few(programmers) could write web pages. • This was web 1.0
- 10. • The concept of "Web 2.0" began with a conference brainstorming session between O'Reilly and MediaLive International in 2004 • Emphasizing tools and platforms that enable the user to Tag, Blog, Comment, Modify, Augment, Rank, etc. • The more explicit synonym of "Participatory Web” or “Read/Write web” Introduction

Web 2.0 services and tools: • Social networks (facebook, orkut, myspace, friendster) • Web-based applications (Google docs, TimeTracker) • Wikis (wikipaedia) • Blogs, photologs or podcasts (blogger, Wordpress) • Social bookmarking (digg, del.icio.us) • Communication tools (basecamp, zoho project, meebo) • Subscription systems (bloglines) • Searchers based on tags (flickr, technorati) • ...
- 13. Web 2.0 basic characteristics: • Application used entirely through a web browser (access info) • Users own the data on the site and exercise control (manage info) • Users are encouraged to add value (create info) • Some Social-Networking aspects are included (participate) • A rich, interactive, user friendly interface (easy to use)
- 14. Web-as-information-source Vs Web-as-participation- platform (access info) (access info) (create info) (promote info) (manage info) Access to info (generated by institutions or other users) Add new content (e.g. knowledge, opinion or experience) Share your things (e.g. photos, writings) Control the info (delete, promote, correct or complete) Suming up (vote the best places to travel or interesting blogs) Put your things online (tasks, meetings, gift lists or a list of books) Now, You are the participant
- 15. Blogs: user’s voice on the web A blog is a website where entries are made in journal style and displayed in a reverse chronological order • You write easily everything you want (with or w/o specialized knowledge) • Blogs can allow for comments from readers • Primarily textual, but no restrictions (photos, video, audio, etc.) • Blogs are for communication! • Blogger, Wordpress, Typepad, LiveJournal There are at least 70 millions, and growing (2x each 6 months!)

- 19. Tagging ,Tag Cloud, Folksonomies & Social Bookmarking • By ‘tagging’ articles, pages, blog posts, etc., the lay person can easily organize data in terms they understand • Folksonomy - collaborative tagging, social classification, social indexing, and social tagging • Folksonomy = folk + taxonomy , hence a folksonomy is a user generated taxonomy = user defined labels/tags to organize information o Del.icio.us o Furl o Flickr

- 24. The Internet Economy… The Long Tail Effect Freemium Business Model • Amazon.com , Netflix.com • Significant profit – out of selling small volumes of hard- to-find items to many customers, instead of only selling large volumes of a reduced number of popular items • Offer basic services for free • Charge a premium for advanced or special features • 37 Signals – a success story • SEO = Search Engine Optimization • PPC = Pay Per Click • Affiliation The Internet Marketing Market
- 25. Technology matters… • AJAX = Asynchronous Javascript And XML • XML = Extensible Markup Language • RDF = Resource Description Framework • REST = Representational State Transfer • SOAP = Simple Object Access Protocol • XHTML = Extensible HTML • SVG = Scalable Vector Graphics
- 26. Wat’s thr ? 4 us! “The Software Guys”
- 27. • A range of web based software programs • Software allows user to interact and share data with others • Open APIs, service oriented design • Collaborative Software Social Software?
- 28. • Services, not packaged software, with cost-effective scalability • Control over unique, hard-to-recreate data sources that get richer as more people use them • Trusting users as co-developers • Harnessing collective intelligence • Leveraging the long tail through customer self-service • Software above the level of a single device • Lightweight user interfaces, development models, and business models Some Principles…
- 29. No Products but Services “There are no products, only solutions” • Not what customer wants but why they want • A problem solving approach • Simple Solutions
- 30. Customization/Personalization • 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
- 31. 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
- 32. Harnessing Collective Intelligence.. Some systems,designed to encourage participation • Pay for people to do it • Get volunteers to perform the same task o Inspired by the open source community • Mutual benefits e.g. P2P sharing
- 33. Specialized Database • Every significant application to date has been backed by a specialized database o E.g. Amazon, Google, Ebay • Database management is the core competency of Web 2.0 companies • “infoware” rather than merely “software”
- 34. End of the Software Release Cycle • “Release Early and Release Often” • Perpetual BETA = software which never leaves the development stage of beta • Daily operations must become a core competency • Software will cease to perform unless it is maintained on a daily basis
- 35. 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
- 36. 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.
- 37. 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
- 38. Why Web 2.0 ? • Cognitive Surplus • Participation • Personalization • People Oriented
- 40. Web 3.0 • This term has been coined to describe the Semantic Web • It promises to “organize the world’s information” • Can reason about information and make new conclusions
