TIME PoY 2006 Call for nominations

In 2006 the call for nomination was widely circulated.

Its at YouTube

http://www.youtube.com/watch?v=IzsV-iBVp38

Who did they select as the Person of the Year 2006?

Why are You the Person of 2006?

According to TIME [Grossman, 2006]: Its a story about communityand collaboration on a scale never seen before. Its about the cosmiccompendium of knowledge Wikipedia and the million-channel peoples networkYouTube and the online metropolis MySpace. Its about the many wrestingpower from the few and helping one another for nothing and how that will notonly change the world, but also change the way the world changes.

The new Web is a very different thing. Its a tool for bringing togetherthe small contributions of millions of people and making them matter. SiliconValley consultants call it Web 2.0, as if it were a new version of some oldsoftware. But its really a revolution.

Who are these people?Who has that time and that energy and thatpassion?The answer is, you do. And for seizing the reins of the global media, forfounding and framing the new digital democracy, for working for nothing andbeating the pros at their own game, TIMEs Person of the Year for 2006 is you.

What is that Thing Called Web 2.0?

The term Web 2.0 was coined by OReilly Media in 2004

Web 2.0 is the second generation of Internet-based services

such as social networking sites, wikis, communication tools, and

folksonomies

that emphasize online collaboration and sharing among users.

First used as a title for a series of conferences

since 2004 some technicians and marketers adopted the phrase...

Its exact meaning remains open to debate Some experts, notably Tim Berners Lee, have questioned

whether the term has meaning...

Web 2.0 Definition

According to Tim OReilly:Web 2.0 is the business revolution in the computer industry caused by the moveto the internet as platform, and an attempt to understand the rules for successon that new platform. Chief among those rules is this: Build applications that

harness network effects to get better the more people use them. (This is whatIve elsewhere called harnessing collective intelligence.)

13/38


Web 2.0 Definition (contd)

Alternative definition: Dont fight the internet

Ironically, Tim Berners-Lees original Web 1.0 is one of the most

Web 2.0 systems out there!

The early web completely harnesses the power of usercontribution, collective intelligence, and network effects.

With the rise of e-bussiness (Web 1.5, the dotcom bubble)

people tried to make the web into something else

That is, they fought the internet, and lost...


14/38


Different Web 2.0s

Web 2.0 may mean different things in different contextes:

The transition of websites from isolated information silos to

sources of content and functionality, thus becoming computing

platforms serving web applications to end-users

A social phenomenon embracing an approach to generating anddistributing Web content itself, characterized by open

communication, decentralization of authority, freedom to share

and re-use, and the market as a conversation

Enhanced organization and categorization of content,emphasizing deeplinking

A rise or fall in the economic value of the Web, possibly

surpassing the impact of the dot-com boom of the late 1990s

Just take your pick!


15/38


Web 2.0 Check-list

Some characteristics

User generated content

Incentive for users to add value to the application as they use it

Social networking effects Public good: no barriers to access, nor to contribute

Networking effects of the web (only a browser is needed)

Rich, interactive, user friendly interface (e.g. AJAX)

Web 2.0 is a vague term (at best)

There are no sharp boundaries, site are Web 2.0 to a greater or

lesser extent

Example: Wikipedia

http://wikipedia.org

Wikipedia is a multilingual, Web-based, free content

encyclopedia project. Wikipedia is written collaboratively by

volunteers; with rare exceptions, its articles can be edited byanyone with access to the Web site. The name is a

portmanteau of the words wiki (a type of collaborative website)

and encyclopedia.

Wikipedia was launched as an English language project onJanuary 15, 2001.

It has over six million articles in 250 languages, including 1.6

million in the English-language edition.

Example: YouTube

http://youtube.com

YouTube is a popular free video sharing website which lets users

upload, view, and share video clips. Videos can be rated; the

average rating and the number of times a video has beenwatched are both published.

The wide variety of site content includes movie and TV clips

and music videos, as well as amateur content such as

videoblogging and short original videos. Founded in February 2005. In October 2006, Google Inc.

announced that it had reached a deal to acquire the company

for US$1.65 billion in Googles stock.

Example: MySpace

http://myspace.com

MySpace is a social networking website offering an interactive,

user-submitted network of friends, personal profiles, blogs,

groups, photos, music and videos. MySpace also features aninternal search engine and an internal e-mail system.

The service has gradually gained more popularity than similar

websites to achieve nearly 80 percent of visits to online social

networking websites. It has become an increasingly influential part of contemporary

popular culture, especially in English speaking countries.

Course Description (blah blah blah)

Het Web bevat een hoeveelheid informatie van ongeevenaarde grootte, en groeit nogsteeds gestaag. Maar behalve gegroeid, is het Web zelf ook van karakter veranderd;de term Web 2.0 wordt gebruikt om dit aan te duiden. Deze module behandelt eenaantal belangrijke aspecten van het Web van de nabije toekomst, in vergelijking methet eerste generatie Web en met de traditionele informatieaanbieders. Gebruikerszijn niet langer passieve consumenten, maar leveren zelf een cruciale bijdrage aan

de informatie. Wikis en andere online samenwerkingsomgevingen zijn een evidentvoorbeeld, maar ook blogs (web logs) stellen iedereen in staat om onbeperktte publiceren. De betrouwbaarheid van informatie blijkt, vooral dankzij socialecontrole, niet onder te doen voor traditionele bronnen. Internet zoekmachines geventoegang tot de informatie of het Web, en vormen een onmisbare schakel tussen

gebruiker en inhoud, en een goede ranking bij zoekmachines maakt het verschiltussen sukses en falen. Het bedrijfsmodel van het Web is ook radicaal gewijzigd,alle populaire Webdiensten zijn gratis toegankelijk, en het belang van traditionelecopyrights lijkt aan erosie onderhevig. Er zijn voorstellen voor een SemantischWeb, waar ook voor computerprogrammas (agents) begrijpelijke informatie wordtaangeboden in een mix van oude en nieuwe inzichten in kennis organisatie. Maar er

zijn ook doem-scenarios: allerlei vormen van SPAM zijn onlosmakelijk verbondenaan het open karakter van het Web.
