What Does "2.0" Mean?
• New energy and direction for the web
• "Web 1.0" was done for users
– created by webmasters, organizations,
businesses, and web-savvy individuals
• Web 2.0 done more by users
– sharing MY almost anything
– personal preferences and ratings of content
– transparency, openness, secrets bared
– users create new content and tools
Trust in the
"Wisdom of Crowds"
• Ordinary people – anyone – can build content
– tagging – unpredictable, unplanned access
– anyone welcome to comment
– wikis express group intelligence
• Sharing the unexpected creates interest
– photos, videos, podcasts, book collections
– the personal, the private, the "too much"
• Users create new combo web products
– mashups & remixes
• two disparate web activities married together
– customized search tools
Technology More Varied
•More formats than web pages
– blogs, RSS feeds, wikis, tags
– 3D viewing, animation, draggability
•More than HTML and a web browser
– RSS feed readers
– video viewers
– downloaded desktop tools
– sound equipment
– cameras
– wireless phone access to web services
Easier to Participate and Innovate
• APIs facilitate bridging programs together
– application program interface
• "mash" part of one web service with part of another
• ProgrammableWeb.com
– most popular mashups
– list of over 450 APIs available to create with
– instructions for using most APIs available
• It helps to know a little programming
– based on flexible programming languages
• XML, Ajax, WADL, REST, + other scripting languages
– create an account and play around
– discussion groups offer help
– copy & paste from View Source
Shift In Values
•Non-hierarchical
– all users equally entitled to participate
– content not vetted
– author often anonymous or cloaked
– what gets used = what's worthwhile
•Pragmatic
– speed and ease of use more than authority
– good enough is good enough
– common sense decides
Discussion
•What would you add
to this sketch of
what Web 2.0
means?
Exercise 1
Getting your del.icio.us
Account Working
Tags and Tagging
• One-word keywords
– describe what something "means" to you
• Open ended
– multiple tags for an item
• Searchable
– find within your tagged stuff
– in everyone else's
• Popularity ranking with human intelligence
Let’s take a look
Dos and Don'ts of Tagging
• Use tags other people use
– create unused tags sparingly
– promotes sharing and comparing
• Use single words or merged words – no space
software
opensource
open_source
• Use two tags for intersecting concepts
canada politics
NOT canadapolitics
• Avoid most punctuation
– spaces separate tags in del.icio.us - NOT commas
– use – and _ only if preferred by others
• Take time to write brief descriptions – searchable
• Take time to edit or change badly chosen tags
• If collaborating, coordinate tag taxonomy
Exercise 2
Using Your del.icio.us Account
Cheat Sheet #1: Getting the Most from del.icio.us
Other Uses for del.icio.us

valuable

Exercise 4
Finding Custom Search
Engines (CSEs)
New Types of Web Pages:
Blogs, Wikis, & RSS Feeds
Blogs, Wikis
•Two special formats to group-related content
– viewable in any web browser
– individual pages found in web searches
•Content from participants, the "WE" web
•Easy to create and to keep current
– little knowledge of coding
– log in and make updates
Blogs (the "Blogosphere")
• Short for "weblog"
– short "postings" - newest on top
– usually a searchable archive
– readers can comment, not edit
• Generally personal or by a small group
– opinions, news, facts, musings
– many powerful experts, authorities
– some junky and commercial ("splogs")
• You must evaluate
– assess the blogger's voice
Finding Blogs
• Web search engines
– include blog in your search:
ala 2007 seattle blog
• Special blog indexes
– more current than search engines
– beware of spam - ads and stolen content
• Google blog search – inblogtitle: to focus
• Technorati – search.technorati.com - "a lot of authority"
– IceRocket – attempt to compete with Technorati
• Ask.com – Blogs & Feeds search
• Use blog CSEs

• Read blogs that your favorite bloggers read
Wikis
• "wiki" – Hawaiian for fast

– focus on content, often gray appearance
– collaboration, sharing, pooling knowledge
• Ownership flat compared to blogs

– challenge: get others to contribute
• May be too open for some purposes
– need to trust contributors, allow editing
– can be vandalized or spammed
Some Successful Uses of Wikis

Bloglines: search for feeds: table of contents
The RSS expert:
Tara Calishain, Information Trapping (New Riders, 2007)
