Web 1.0 – the Read Only Web
Origins of the Web Invented by Tim Berners-Lee in 1989 First Web Browser – October 1990 First Web Server – November 1990 (nxoc01.cern.ch )
Tim Berners Lee’s Vision:“The dream behind the Web is of a common information space in which we communicate by sharing information. “
What we got: Brochureware!
General attributes: Fairly static information Updated infrequently Typified as ‘Brochureware’
Elements of web page: Images, navigation icons, text, menu
Writing style: Impersonal, professional, descriptive, statements of fact
Linking structure: Minimal, unchanging, little interaction between sites

The Burst of Dotcom Bubble Why Web 1.0 failed?
Misunderstood the Web’s dynamics Relied on old software business models Locked in users with APIs Software sold as an application not a service Sold to the Head, not to the Tail
Failed to harness the Wisdom of CrowdFocused purely on size of index; Relevance was ignored; By 1997, only 1 of the top 4 search engines could find itself! Web Search seen as hopeless
Ignored their key asset It’s Data, not the software
Ignored the power of network effects The more people use a networked service, the more useful it becomes
Saw the Web as publishing, not participation Read-Write Web, not Read-only Web
Survivors: Google, Amazon, EBay What they did correctly then, is today known as Web 2.0 Tapped in to the Web’s dynamics (Long Tail, Social Data & the Wisdom of the Crowd)

Web 2.0
"Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform:
delivering software as a continually-updated service that gets better the more people use it
consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others
creating network effects through an "architecture of participation,“ and going beyond the page metaphor of Web 1.0 to deliver rich user
experiences.“
Web 2.0’s Long Tail Examples Search Keywords
20-25% of Google’s queries have never been seen before Google AdSense
Extend advertising to publishers way down the long tail of websites Amazon
Average Barnes & Noble carries 130,000 titles. More than half of Amazon's book sales come from outside its top130,000 titles. iTunes
Every track of its 2 million tunes has sold at least once Netflix
95% of its 55,000 DVDs rented only once a quarterDepartment of Management Studies, IIT Madras
Social Side of Web 2.0Let your users create your data
Amazon’s reviewsDel.icio.us’s bookmarksFlickr’s photosYahoo, Google’s indexed web pagesTechnorati’s blogsFriendsReunited’s friendsWikipedia’s information
Harnessing the Wisdom of Crowd Decisions by the many better than decisions by one
Examples: Trends (Twitter) Recommendations (Amazon) Tagging (Del.icio.us, connotea.com) Voting systems (Digg.com, Reddit.com) Blogging (Collective attention of the blogosphere selects for value) Search Engines (Google’s PageRank)
