Do you: ● Know what is a blog? ● Keep a blog? ● Know what RSS is? ● Use a news (RSS) reader (such as bloglines.com)? ● Know what a wiki is? ● Write on a wiki (at least once)? ● Know what del.icio.us is? ● Use del.icio.us? ● Know what Flickr.com is? ● Use Flickr.com? ● Use Slashdot.org? Digg.com? ● Know how Google ranks pages and decide what is relevant? ● Know Google maps?

What is “Web 2.0”? 'I don't know what you mean by quot;gloryquot;,' Alice said. Humpty Dumpty smiled contemptuously. 'Of course you don't—till I tell you. I meant quot;there's a nice knock-down argument for you!quot;' 'But quot;gloryquot; doesn't mean quot;a nice knock-down argumentquot;,' Alice objected. 'When I use a word,' Humpty Dumpty said, in rather a scornful tone, 'it means just what I choose it to mean— neither more nor less.' 'The question is,' said Alice, 'whether you can make words mean so many different things.' 'The question is,' said Humpty Dumpty, 'which is to be master—that's all.'

What is “Web 2.0”? Non capisco che cosa volete intendere dicendo quot;gloriaquot; – disse Alice. Humpty Dumpty sorrise con aria di superiorita'. E' naturale che tu non capisca .... finche' non te lo spieghero' io. Volevo dire che quot;questo e' un ottimo argomento per darti torto!quot; - Ma quot;gloriaquot; non significa quot;un ottimo argomento per darti torto!quot; - obietto' Alice. Quando io adopro una parola - disse Humpty Dumpty con tono piuttosto sdegnoso - essa ha esattamente il significato che io le voglio dare .... ne' piu' ne' meno. Bisogna vedere - disse Alice - se voi potere fare in modo che le parole indichino cose diverse. Bisogna vedere - disse Humpty Dumpty - chi e' che comanda ... ecco tutto.

The term “Web 2.0” ● When is a string a word? – More than 13,000,000 Web page mention “web2.0” (can I summarize them in 1 hour?!?) http://www.google.it/search?q=web2.0 – Buzzword? ● Agreed word for agreed meaning? Not really ● DISCLAIMER: this is my take on the trend. – Adoption of new words in our new fast world is an interesting topic but not the topic of this talk ;-) ● http://www.google.com/trends?q=web2.0%2C+ajax+javascript%2C+folksonomy%2C+m ashup%2C+podcasting&ctab=0&geo=all&date=all ● WARNING: the presentation is buzzwords- plenty!

Outline of the talk ● Disclaimer: Web2.0 is an evolving buzz-trend ● History of the term Web2.0 ● Key concepts – User participation – Web as platform (API, mashups) – Interactivity (ajax) ● Examples: – del.icio.us, flickr, blogs, wikipedia, ... ● And the future?

Web 2.0: history of a meme ● First things first: what is Web1.0? ● Dotcom bubble ● In 2001 there was the Dotcom burst ● BUT the Web, “far from having quot;crashedquot;, was more important than ever, with exciting new applications and sites popping up with surprising regularity”

● “What's more, the companies that had survived the collapse seemed to have some things in common. Could it be that the dotcom collapse marked some kind of turning point for the web, such that a call to action such as quot;Web 2.0quot; might make sense?” ● Which web1.0 experiences survived? And why? – Amazon – Ebay – Google

Amazon.com vs BarnesAndNobles Amazon let users add value: Explicit: Ratings, Reviews Implicit: Collaborative filtering of buying behaviour data Affiliation programs: set up your own Amazon.com shop The value of this database is given back to the community On-site marketing is completely based on wisdom of the crowd BN.com had a brand, Amazon had a platform! From i-merge slides

Ebay •Value of the platform increases with every new participant •Providing an ecosystem where everybody gets a piece of the cake •Long tail business model •Integrating social realities at the heart of the architecture: Reputation, Trust,… •What is the asset of Ebay? From i-merge slides

Ebay (2) From i-merge slides

Google • Search engine war won based on maximizing the intelligence of its user base: PageRank system, which has two rules: 1.Hyperlinks are votes of attention 2.Some voters weigh more than other voters, because they themselves are heavily linked to • Implicit harvesting the distributed intelligence of the network • Google bombing = communities that exploit this algorithm: – e.g: “miserable failure” or “buffone” or “incapace” or “regali” From i-merge slides

Who invented the “web2.0” term? Tim O’Reilly “Those companies who survived the dotcom burst knew how to build an environment in which users could participate, although the nature of that participation isn’t always clear” What Is Web 2.0 - Design Patterns and Business Models for the Next Generation of Software - by Tim O'Reilly 09/30/2005 www.oreillynet.com/pub/a/oreilly/tim/news/2005/09/30/what-is-web-20.html

Web2.0 ~ social web ● I prefer the term “social software” or “social web” ● But ... who am I?

Web1.0 --> Web2.0 WEB 1.0: We thought the web was about publishing, advertising and « multimedia » WEB2.0: The web as a platform User participation built in the very heart of it Users add value (from i-merge slides)

Web2.0 key concepts ● The web as a platform – “the service automatically gets better the more people use it” – quot;architecture of participationquot; ● Harnessing Collective Intelligence / Wisdom of the crowds – Users contribute and add value (wikipedia, del.icio.us, flickr, digg, youtube, free software/open source, blogs, ... readwrite web ... cornucopia of the commons)

The web as a platform: what is a platform? A digital environment On which users can interact with data and/or with eachother Thereby creating added value for themselves or for the platform as such The architecture of the platform determines the nature of this participation and the value that results from this participation A platform can focus on the individual, the collective, the data or a common goal (a virtual world?) (from i-merge slides)

Examples ● Let us explore some examples ● And try to find the common patterns

Bookmarking is so Web1.0 ● From personal bookmarking ... Image from http://www.ethanzuckerman.com/blog/?p=512

Del.icio.us ● ... to social bookmarking Image from http://www.ethanzuckerman.com/blog/?p=512

Del.icio.us (2) ● A small difference (bookmarks are public by default) made a huge difference! ● You can be informed of what your “friends” (people you trust and admire) bookmark! ● You can see what is popular at the moment! Image from http://www.ethanzuckerman.com/blog/?p=512

Tags ● How do they work on del.icio.us? ● Screenshot! ● ●

Tags ● You can see which other users used the tag “sociology”! Or the new made-up tag “sociologytn”!! – Leads to new interesting links – Leads to users who are doing similar things (possible future friends and partners!) ● ● ●

Tags •Other users who bookmarked this same link – Leads to users who are doing similar things ( discovery) – They also gave other tags to this link ( increasing semantic field) – They bookmarked other links ( inspiration)

Tags ● Users contribution is a must! Simplicity is key! ● Folksonomy (flat strings, no structure). ● Before there was taxonomy (Yahoo!) Image from http://www.ethanzuckerman.com/blog/?p=512

Other uses of tags ● And also flickr, youtube, last.fm, citeulike, .... ●

Blogs ● Some examples

Blogs: As easy as email! Image from http://www.ethanzuckerman.com/blog/?p=512

Blogs (2) ● RSS – Extremely SIMPLE! --> adoption | what about the Semantic Web? OWL?!? Microformats is a simpler, evolutionary approach

RSS readers ● Bloglines screenshots

RSS: only from blogs? ● Joking? ● Repubblica, cnn ● Search on google (pubsub better) ● Events ● Everything (that) is a list, everything is a list

Wikipedia Like Britannica Encyclopedia??? Image from http://www.ethanzuckerman.com/blog/?p=512

Wikipedia ● User-contributed encyclopedia. Everyone can create new concepts or edit old ones!!! Would have you bet on this mechanism 5 years ago? Revisit “what is possible” and “what not”. Users contribution! Like free software but for content! Image from http://www.ethanzuckerman.com/blog/?p=512

Neutral Point of View ● An interesting (sociologic?) challenge: “can we all (!) agree on the meanings of words?” Edit wars are extremely insightful! Have a look at the “history” page to see users contributions Image from http://www.ethanzuckerman.com/blog/?p=512

Wikipedia software ● It is MediaWiki (http://mediawiki.org) – There are tons of other free software wikis tools (moinmoin, pmwiki, ...) ● Download the software (Free software) and create your own. – Great for collaborative writing (a book?) and for documentation – Move everything you write (your company?) on a wiki! – www.sociologiatrento.it/wiki ?

Digg ● Skip it? ● ● Decentralized Users contribution allows to spot what is cool. Democratic? Wisdom or herd behaviour? What gets “noticed”? (“sex” or “africa”?) ● Slashdot.org has similar dynamics ● Other ways to discover “interesting stuff”: del.icio.us/popular, flickr interestingness, ..., blogpulse, cloudalicious ●

Mashups • Websites that are built from pieces of other websites (that expose simple and useful APIs) – RSS google maps, last.fm, ... web services • http://www.webmonkey.com/webmonkey/06/08/index4a_pag e2.html?tw=commentary • http://www.programmableweb.com/api/Flickr/mashups • Ex: http://krazydad.com/colrpickr/index.php?group=colorfields • Is Flickr worst off or best off if a lot of other cool services use “its” images? • BE OPEN! EXPOSE DATA VIA SIMPLE APIS!

Mashups (combining info from different sites) ● Technorati http://technorati.com/tag/sociology sociologia ● http://popurls.com/ – Who created this content? ● More? http://programmableweb.com/

Mashups (combining info from different sites) ● Craiglist + gmaps http://www.housingmaps.com/ ● Gmaps +ebay http://www.markovic.com/markovic.com/ebay/search.php ● Gmaps+georss+flickr+geocaching+... http://www.dynamite.co.uk/local/ ● Gmaps+... http://mibazaar.com/missingkids.html ● gmaps+realtimetrains http://dartmaps.mackers.com/ ● Gmaps+ news on cartoon riots http://www.lastingnews.com/maps/cartoons_protests.html ● Gmaps + your friends ? ● http://berkeleyca.crimelog.org/all ● http://maps.google.com/green/gg_interior_sf.html

AJAX ● AJAX (Asynchronous JavaScript and XML) is a Web development technique for creating interactive web applications. ● Web applications will replace desktop application: Gmail , Google Calendar, Meebo, Kiko, Writely, Pixoh, and DabbleDB. ● How can I find cool examples? http://del.icio.us/popular/ajax ● http://www.pageflakes.com/ ● http://digg.com/spy

Writely (google)

Greasemonkey ● There are so many data out there, why not play with them? ● Greasemonkey let you easily do this! – Javascript + XHTML DOM model

Licence ● Some Rights Reserved! ● Content protection (like the default copyright of everything you produce!) limits re-use and prevents experimentation. ● Creative commons allows you to state “some rights reserved”. I would suggest – CC Attribution-ShareAlike 2.0 licence – http://creativecommons.org/licenses/by-sa/2.0/ – Allows commercial use of your content

Summary? ● What ties everything together? ● Social relationships – Links (a la google) – Trust (friendship) relationships on social web (not only ebay in which reputation~money, slashdot, google, epinions, flickr, ...) ● All the successful Web2.0 ventures are exploiting humans need to be connected and recognized, and the network effect. ● Social capital, reputation economy, ... – “Down and out in the magic kingdom”, sci-fi novel by Cory Doctorow ● “It's all about you” (everything is public) ... and your relationships!

Marketing2.0 ● Companies (brands) are really interested in this new social architecture, it is a total shift from previous ones – Tv, radio, newspapers are one-to-many (broadcast) [people are passive swallowers] – Blogs, Web2.0 is many-to-many [people are active, they contribute (We Media)] ● Advertisement does work nomore, pay attention to what people say, they can destroy your reputation. – Word of mouth, viral marketing – P2p advertisement (hidden persuaders in plain sight?)http://www.stayfreemagazine.org/public/nyt-rob-walker.html

Summary? The web as a platform User participation built in the very heart of it Users add value ● Bottom-up ● Democratic (anarchic?) ● On the shoulders of your peers (not necessarily giants!) --> Evolutionary (towards the best?) --> Smartmobs (book by Rheingold) ● Inclusive ● Easy to be engaged

Where do we go from here? ● What will be Web 3.0? Who will define it? ● ItalianWeb2.0 ?!? ● Or better, what will be the next “buzzword”, able to shape how the world think about the world? ● Contribute2.0 ;-)
