Transcript of "Interactive Innovation Through Social Software And Web 2.0"

  1. 1. Interactive innovation through Social Software and Web 2.0 Thomas Ryberg PhD student e-Learning Lab, Department of Communication and Psychology [email_address] http://www.ell.aau.dk Made with Web 2.0 Logo-creator: http://msig.info/web2.php
  2. 2. Outline <ul><li>Web 2.0 and social software – core points </li></ul><ul><li>Demonstration and showcases of “Web 2.0 and social software” services and software </li></ul><ul><ul><li>The technological perspective </li></ul></ul><ul><ul><li>The conceptual perspective </li></ul></ul><ul><li>Interactive Innovation – my spin on this: </li></ul><ul><ul><li>User generated content, user driven innovation, hackability, widgetality and the perpetual beta! </li></ul></ul><ul><li>A small task for you : </li></ul>
  3. 3. Task <ul><li>Imagine/Create an internet based service that works on mobile devices – must take into account: </li></ul><ul><ul><li>Location </li></ul></ul><ul><ul><li>A social graph with connections/relations and exchange of content . </li></ul></ul><ul><ul><li>Bring in data/services from other sites </li></ul></ul><ul><li>You are very welcome to relate it to or base it on your project work </li></ul>
  4. 4. Web 2.0 and SoSo
  5. 5. Web 2.0 and social software <ul><li>Have you heard about and know the terms? </li></ul><ul><li>What’s the fuzz?? </li></ul><ul><ul><li>Web 2.0 refers to a second generation of services available on the internet that let people collaborate , and share information online. They often allow for mass publishing (web-based social software). The term may include blogs and wikis . To some extent Web 2.0 is a buzzword, incorporating whatever is newly popular on the Web (such as tags and podcasts ), and its meaning is still in flux. Adapted from: http://en.wikipedia.org/wiki/Web_2.0 </li></ul></ul><ul><li>May be a lot of buzz – but it’s buzz that’s supported and developed by Google, Yahoo and Microsoft…  </li></ul><ul><li>Also the entire media landscape in DK has been re-organised to accommodate to ‘user generated content’ or ‘citizen journalism’! ( www.nationen.nu , luftskibet.information.dk, computerworld.dk, ditcentrum.dk) </li></ul><ul><li>Should we understand this as software and services or as a conceptual framework? </li></ul>
  6. 6. “ Web 1.0”  “Web 2.0” Web 1.0 Web 2.0 Some Examples: www.furl.net , www.elgg.net , http://www.librarything.com Matrice above adapted from: http://www.oreillynet.com/pub/a/oreilly/tim/news/2005/09/30/what-is-web-20.html Ofoto Flickr Akamai BitTorrent mp3.com Napster Britannica Online Wikipedia Personal websites Blogging Web services publishing Participation Content management systems Wikis Directories (taxonomy) Tagging (&quot;folksonomy&quot;) Stickiness Syndication (RSS, XML)

  9. 9. Key differences between Web 1.0 and Web 2.0 <ul><li>Users as first class entities in the system </li></ul><ul><ul><li>prominent profile pages featuring e.g: age, sex, location </li></ul></ul><ul><ul><li>Testimonials, or comments about the user by other users. </li></ul></ul><ul><li>The ability to form connections between users </li></ul><ul><ul><li>links to other users who are “friends” membership in “groups” </li></ul></ul><ul><ul><li>subscriptions or RSS feeds of “updates” from other users </li></ul></ul><ul><li>The ability to post content in many forms: photos, videos, blogs </li></ul><ul><ul><li>Comments and ratings on other users’ content </li></ul></ul><ul><ul><li>Tagging of own or others’ content </li></ul></ul><ul><ul><li>Some ability to control privacy and sharing. </li></ul></ul><ul><li>More technical features, including a public API to allow third–party enhancements and “mash–ups,” </li></ul><ul><ul><li>embedding of various rich content types ( e.g. , Flash videos), and communication with other users through internal e–mail or IM systems. </li></ul></ul>Key differences between Web 1.0 and Web 2.0 by Graham Cormode and Balachander Krishnamurthy First Monday , Volume 13 Number 6 - 2 June 2008 http://www.uic.edu/htbin/cgiwrap/bin/ojs/index.php/fm/article/viewArticle/2125/1972
  10. 10. Web 2.0 core point <ul><li>Technological dimensions: </li></ul><ul><ul><li>Blogs, podcast, wikis, tags RSS-feeds, web as platform (Ajax, Java-script) </li></ul></ul><ul><ul><li>Rich Internet Applications (RIA) – Google docs, web-office </li></ul></ul><ul><li>Conceptual dimensions </li></ul><ul><ul><li>User Generated content - but rather than finished materials/data - ongoing evolving streams and continuous ‘dialogues’ </li></ul></ul><ul><ul><li>User ratings/reviews </li></ul></ul><ul><ul><li>Folksonomies </li></ul></ul><ul><ul><li>Sharing, collaborating, exchanging </li></ul></ul><ul><ul><li>Bottom-up – architecture of participation </li></ul></ul><ul><ul><li>Easier exchange (technological) - aggregation and distribution </li></ul></ul><ul><li>Popular services </li></ul><ul><ul><li>Social networking sites (myspace, facebook, del.icio.us) </li></ul></ul><ul><ul><ul><li>Ego-centric – personal networks around profiles </li></ul></ul></ul><ul><ul><ul><li>Object-centric – networks around shared material </li></ul></ul></ul><ul><ul><li>Personalised resource centers (Igoogle, Live-servies, Yahoo 360) </li></ul></ul><ul><ul><ul><li>Aggregation of media, ressources and ‘news’ </li></ul></ul></ul>
  11. 11. Ideas about “new” social constellations or aggregations <ul><li>Networks between people working collaboratively </li></ul><ul><li>Networks between people sharing a context </li></ul><ul><li>Networks between people sharing a field of interest </li></ul><ul><li>(Dalsgaard, 2006): </li></ul><ul><li>http://www.eurodl.org/materials/contrib/2006/Christian_Dalsgaard.htm </li></ul>Picture taken from: (Andersson, 2008) http://terrya.edublogs.org/2008/03/17/networks-versus-groups-in-higher-education/ Learner in the centre Let’s briefly explore some examples of this – there are however many other sites and mixes
  12. 12. Stigmercy Picture taken from: (Andersson, 2008) http://terrya.edublogs.org/2008/03/17/networks-versus-groups-in-higher-education/ Stigmergy is a mechanism of spontaneous, indirect coordination between agents or actions, where the trace left in the environment by an action stimulates the performance of a subsequent action, by the same or a different agent. Stigmergy is a form of self-organization . It produces complex, apparently intelligent structures, without need for any planning, control, or even communication between the agents. http://en.wikipedia.org/wiki/Stigmergy
  13. 13. Youtube – User Generated Content <ul><li>Most popular example of user generated content </li></ul><ul><li>Object centric but also profile based </li></ul><ul><li>Genre mix, creativity, comments </li></ul><ul><li>Typical features, one can embed videos other places, easily share, have a list of personal favourites and playlist – user ratings </li></ul>
  14. 14. User Generated Relevance – user ratings & reviews <ul><li>Front page decided by collective of users (and advertisers) </li></ul><ul><ul><li>Youtube, Digg, delicious, flickr </li></ul></ul><ul><li>Invisible collective or aggregation of non-coordinated actions are co-creating the sites (stigmercy) – e.g. through software-algoritms </li></ul><ul><ul><li>Tag-clouds </li></ul></ul><ul><ul><li>Popular videoes </li></ul></ul><ul><ul><li>But also: </li></ul></ul><ul><ul><li>Creates order in chaos (clusters) </li></ul></ul><ul><ul><li>Creates new relations and connections (or re-create existing) </li></ul></ul><ul><ul><li>Related tags, related videoes (hot hot hot), related persons (e.g. facebook – if you know you might also want to know) </li></ul></ul>
  15. 15. Social Network Sites <ul><li>Facebook is one of many SNS’ </li></ul><ul><li>What is an SNS? – a broad definition: </li></ul><ul><ul><li>“ We define social network sites as web-based services that allow individuals to (1) construct a public or semi-public profile within a bounded system , (2) articulate a list of other users with whom they share a connection , and (3) view and traverse their list of connections and those made by others within the system . The nature and nomenclature of these connections may vary from site to site.” (boyd & Ellison 2007, min fremhævning) </li></ul></ul><ul><ul><li>“ What makes social network sites unique is not that they allow individuals to meet strangers, but rather that they enable users to articulate and make visible their social networks .” (boyd & Ellison, 2007, min fremhævning) </li></ul></ul><ul><ul><li>boyd, d. m., & Ellison, N. B. (2007). Social network sites: Definition, history, and scholarship. Journal of Computer-Mediated Communication , 13 (1), article 11. http://jcmc.indiana.edu/vol13/issue1/boyd.ellison.html </li></ul></ul>
  16. 16. SNS <ul><li>SNS in an historical perspective </li></ul><ul><li>Back to 1997 but only recently populated and popular on a mass scale </li></ul><ul><li>Until late 2005 the term SNS relatively unknown in DK </li></ul><ul><li>Model fra (boyd & Ellison, 2007) </li></ul>
  17. 17. Individual in the centre – of the network <ul><li>Individual in the centre – profiles with varying degrees of information </li></ul><ul><li>Individual without social network does not make sense (narcissism – I would not agree!) </li></ul><ul><li>All the pages build on different kinds of network </li></ul><ul><ul><li>Ego-centric network </li></ul></ul><ul><ul><li>Objekt-centric network </li></ul></ul>
  18. 18. Connections and relations become visible <ul><li>Relations btw “friends” </li></ul><ul><li>Connections to “groups” </li></ul><ul><li>Comments and ‘testimonals’ - continuum of intimate/personal to neutral/professional </li></ul><ul><li>Connections to content/data (RSS) – updates from others (status, content, location) </li></ul><ul><ul><li>Plazes.com, Twitter </li></ul></ul><ul><ul><li>Events on FB </li></ul></ul><ul><li>Personalised and self-chosen streams of information/data </li></ul>
  19. 19. Lifestreaming, Microblogging <ul><li>Microblogging, livestreaming (facebook status updates on steroids) </li></ul><ul><li>Focus on collecting streams (new FB strategy) – friendfeed, sweetcron mfl. </li></ul><ul><ul><li>Own and others’ streams </li></ul></ul><ul><li>Social phenomenon – network comments, awareness </li></ul><ul><li>Coupled with location – GPS in camera and mobile – lifestream, lifepath ? Lifemapping ? E.g.: http://www.iphonetwitters.com http://www.socialoyster.com </li></ul><ul><li>Business– FB walled garden – takes in loads of data…little comes out! </li></ul>
  20. 20. “ Software” <ul><li>Like regular apps – but they’re online – web-office, calendar, news reader, Web OS etc. </li></ul><ul><li>Also stand alone apps – Google Earth </li></ul><ul><li>Discover, search, location, placeness, closeness </li></ul><ul><li>Collaborative editing, sharing calendars, Social networks – sharing placemarks, layers </li></ul><ul><li>Integration with maps, wikipedia, external sites </li></ul>
  21. 21. Easier exchange of content – RSS, mashups, widgets <ul><li>Through various standards and technologies it has become easier to exchang ‘content’ between different systems </li></ul><ul><ul><li>RSS-feeds (subscribe to what others bookmark, new videoes, news etc.) </li></ul></ul><ul><ul><li>E.g. Youtube videoes can be embedded elsewhere </li></ul></ul><ul><ul><li>Facebook can get info from Friendfeed, Delicious etc. </li></ul></ul><ul><ul><li>One can easilier integrate widgets and mashups on a page </li></ul></ul><ul><li>“ Open” standards, Open APIs give way for WIDGETS – MASHUP </li></ul>
  22. 22. Sharing across different social constellations Homebase(s) – profile PLE Strength of tie Own content Friends’ content Groups’ content Collectives’ content – aggregated other Shared fields of interest – imagined communities Glued together by RSS, Widgets, ‘open standards’, open APIs – Streams of continuously evolving ‘data’ and ‘information’ that can be somewhat easily manipulated We all become entrance points into complex (overlapping) networks
  23. 23. Technological perspective <ul><li>Some of the tech-stuff: </li></ul><ul><ul><li>AJAX that allows web-office – live editing updating (maybe some of you know more?) </li></ul></ul><ul><ul><li>Standards and exchange ’protocols’: RSS, XML, CSS, java-script, Flash, HTML </li></ul></ul><ul><ul><li>OpenAPIs and Open Source Software – not the same, but OpenAPIs and exchange mechanisms open for MashUps </li></ul></ul><ul><ul><li>This results in: aggregation, distribution, widgetality and hackability </li></ul></ul>
  24. 24. The technological perspective <ul><li>Some of all this stuff are new technologies; some are older technologies, which have been popularised e.g. blogs, wikis </li></ul>http://en.wikipedia.org/wiki/Image:Web20buzz.png
  25. 25. <ul><li>Google wants to create an easy way for developers to create an application that works on all social networks. And if they pull it off, they’ll be in the center, controlling the network. </li></ul><ul><li>SOURCE: www.techcrunch.com </li></ul><ul><li>Profile Information (user data) </li></ul><ul><li>Friends Information (social graph) </li></ul><ul><li>Activities (things that happen, News Feed type stuff) </li></ul>
  26. 26. Aggregation, distribution, Hackability <ul><li>Agg/Distr: </li></ul><ul><ul><li>Interoperability of systems </li></ul></ul><ul><ul><li>Import content from other sites or streams into one’s own page through RSS or XML document - tapestries of microcontent </li></ul></ul><ul><li>Hackability </li></ul><ul><ul><li>Code is open or freely available API </li></ul></ul><ul><ul><li>One can create services that draws on Google Maps e.g. Findvej.dk. </li></ul></ul><ul><ul><li>Profiles on some SNS supports HTML, javascript and one can customise the looks, import video from youtube, bookmarks from del.icio.us, create tag-clouds and so on. </li></ul></ul><ul><li>Also becoming available in gadgets and OS’es (Chumby, Xbox, MacOS, Vista – or extensions for FireFox) </li></ul><ul><li>Widgets are the easy way of doing this – mashups are a little harder but great fun! </li></ul>
  27. 27. Widgetality <ul><li>A Web Widget is a portable chunk of code that can be installed and executed within any separate html-based web page by an end user without requiring additional compilation. They are akin to plugins or extensions in desktop applications. Other terms used to describe a Web Widget include Gadget, Badge, Module, Capsule, Snippet, Mini and Flake. Web Widgets often but not always use Adobe Flash or JavaScript programming languages. http://en.wikipedia.org/wiki/Web_widget </li></ul>
  28. 28. Mash-ups <ul><li>By using the possibilites of exchange, distribution and aggregation (refers both to aggregation, but also to specific software mashups) new services/software are created </li></ul><ul><li>E.g. 275 flickr-mashups: http://www.programmableweb.com/api/flickr/mashups </li></ul><ul><li>Or: http://www.programmableweb.com/mashups </li></ul>
  29. 29. MashUps
  30. 30. The conceptual perspective <ul><li>Sharing, collaborating, connecting, networking, identity work – harnessing the power of both weak and strong ties in networks </li></ul><ul><li>Hive-intelligence (stupid term!) – </li></ul><ul><ul><li>Two heads are better than one - one million heads are even better – Wikipedia; no central expert, but distributed intelligence (though questionable) </li></ul></ul><ul><li>Folksonomies – the bottom-up approach – </li></ul><ul><ul><li>the structure and what is important is decided by the users, not a central categorisation unit, what is hot news depends on the users, not an editor </li></ul></ul><ul><li>User-driven innovation and user generated content – </li></ul><ul><ul><li>people upload and share their homemade pictures, videoes, bookmarks, calendars etc. creating ’creative’ personal profiles through use of scripting, widgets, light-weight coding, mashups and so on. </li></ul></ul><ul><li>Funny tension : Copy-left, Open Source, Free software foundation – information should be free vs. We make shit-loads of money on idiots freely giving their videos away and all their personal information (Google, Youtube, Facebook, MySpace etc.) – hence some call it loser-driven innovation  </li></ul>
  31. 31. Social fabric of everyday life <ul><li>Online/offline – makes no sense – the web and web 2.0 for that matter is a continuation, overlap, extension of everyday life </li></ul><ul><li>Virtual/Real – makes no sense: people are real in the virtual, some identity play, but identity is very often tied to location, everyday doings, interests, friends and so on – quite mundane </li></ul><ul><li>The notion of virtual networks as non-places is problematic!! Place, space and location is ALL – closeness, personal, social networks, intimacy </li></ul><ul><li>Here are some citations from Danish Arto users – why they use arto: </li></ul><ul><ul><li>” that I have more contact with my friends… also when we’re together… because then we might talk about something that happened in here…” (Girl, 15) </li></ul></ul><ul><ul><li>” That I won’t lose some of my IRL-friends!” (Boy, 17) </li></ul></ul><ul><ul><li>Why are you using facebook/myspace?? </li></ul></ul><ul><li>The social fabric of the web is tightly related to the local, the place, the location and the creation of a personal, but relational identity </li></ul><ul><li>Barry Wellman terms it: Glocalization – we do become more global, but we do not become less local or grounded </li></ul>
  32. 32. Location based technologies <ul><li>Space, Place and location - Plazes.com </li></ul><ul><li>Location based games – PacManhattan </li></ul><ul><ul><li>http://www.in-duce.net/archives/locationbased_mobile_phone_games.php </li></ul></ul><ul><ul><li>http://en.wikipedia.org/wiki/Location_based_game </li></ul></ul><ul><li>Intermixture between virtual/real </li></ul><ul><li>GPRS, GPS, mobile location (moblogging tied to places, coupled e.g. With google maps) or services like Dodgeball </li></ul><ul><li>GIS: http://www.opensourcegis.org/ </li></ul><ul><li>Web 2.0-based distributed map system for an EU-project on regional economical development: http://www.communitywalk.com/map/159477 </li></ul><ul><li>A Mashup from participants in the PlaceME project: http://mashreality.com/view.html </li></ul>
  33. 33. Interactive Innovation <ul><li>User generated content and innovation – </li></ul><ul><ul><li>Understanding how technologies speak into people’s lives, identities and connects to their streams of experience, their being in the world and connection to others – the social fabric of life! </li></ul></ul><ul><ul><li>Creating architectures of meaningful participation, opportunities for engaging with peers, networks and developing situations, events, life-bits </li></ul></ul><ul><li>Hackability, widgetality – keep it open, modifiable, listen to and understand the users, let them play, hack, modify, develop </li></ul><ul><ul><li>This is equally true for ordinary products – medical equipment, sporting equipment and loads of other products benefit from engaged user communities (Franke & Shah, 2002 - How Communities Support Innovative Activities ) </li></ul></ul><ul><li>The perpetual beta! You’re never done, people’s needs will change, their practices and ways of using the systems will develop and change, which in turn will mean you’ll have to change the systems to accommodate to emerging needs </li></ul><ul><li>New ways of organising and managing development and innovation – www.cofundos.org – also the Linux community has (I have been told) created a new way of adding updates – from hierarchy to distributed, networked ’voting’ system – building on reputation and social capital of the programmer (anybody knows more?) </li></ul>
  34. 34. Gluing and weaving of systems Bibsonomy Bloglines Flickr MySpace YouTube Furl Dodgeball Librarything Web 2.0 -systems – gluing and weaving together different content, services and systems
  35. 35. Some references <ul><li>http://en.wikipedia.org/wiki/Web_2.0 </li></ul><ul><li>http://en.wikipedia.org/wiki/Social_Software </li></ul>
  36. 36. Task <ul><li>Imagine/Create an internet based service that works on mobile devices – must take into account: </li></ul><ul><ul><li>Location </li></ul></ul><ul><ul><li>A social graph with connections/relations and exchange of content . </li></ul></ul><ul><ul><li>Bring in data/services from other sites </li></ul></ul><ul><li>You are very welcome to relate it to your work </li></ul>
