What If We’re Wrong?
Developing A Sustainable Approach to the
Use of Web 2.0
About This Talk
Many members of JISC Emerge community are active
in exploiting the potential of various Web 2.0
technologies and approaches
But what if the Web 2.0 sceptics are raising legitimate
concerns? How should we go about developing a
sustainable approach to use of Web 2.0?

We’re taking photos at
events & sharing them on
Flickr, Facebook, …:
• Builds community
• Shared experiences
• Shared memories
• It’s fun
• …
But what about:
• Data protection
• Privacy
• Embarrassment
• …
How should we respond?

Possibly A Big Issue
A recent item
published on BBC
News Web site
(17 April 2008)
Is photography
not only an issue
for our sector in
our context, but
have legal
implications?
Do we need:
• Formal
agreements
• Model T&Cs
•…
Amplified Events
What I Do
My approach (note IANAL):
• Be open
• Clarify what I mean by this:
 CC licence on materials (title slides, handouts,
on Slideshare, …)
 CC licence on talk
 Permission to video / record / video
 Warning that licence may be rescinded if
disasters happen!
• Invitation to others to take a similar approach
Approach described at Stargazing conf, Edinburgh Univ, Nov 2006.
“Legal issues are important” said Charlotte Waelde “and Brian’s
demonstrated lightweight ways of addressing such issues” 

When I’m An Organiser
Approaches taken at recent “amplified events”:
• IWMW 3-day events since 2006
• Exploiting Potential of Wikis and Exploiting
Potential of Blogs & SNs 1-day workshops
We:
• Published an AUP and risk assessment details
• Notified speakers that event would be videoed &
broadcast & sought permission
• Provided guidelines for session chairs: informing
audience of remote audience, repeating
permissions from speakers
• …
Being open about issues has proved fine (so far)
Amplified Events
When I’m In The Audience
Participant at Oxford Beyond Digital Natives conf, April:
• Asked speaker for permission to record:
 OKish, but reconfirm after talk. Subsequent request not to
publish – no problem
• Asked fellow debates for permission – fine
• Student panel. No opportunity to seek prior
permission so videoed 10 mins & then told them:
 Students were happy
 Two students were 6th formers
 Sought them (all) out & gave card and asked for
agreement (they need to opt in)
 Organiser & participant asked me not to publish /
told me it was illegal; head’s permission needed; …
 No email received, so video not published
What should be done? Are there lightweight approaches?

What If Things Go Wrong?
Speaker doesn’t want to be recorded?
Things go wrong in live presentation?
Speaker changes mind afterwards?
Father Jack is in the audience?
Gun-toting member of audience goes beserk?

What If Things Go Wrong?
Speaker doesn’t want to be recorded?
• That’s fine (and avoid pressuring speaker)
Things go wrong in live presentation?
• Accept it: that’s life & audience normally supportive
Speaker changes mind afterwards?
• That’s fine – use of lightweight approaches help
Father Jack is in the audience?
• Don’t worry, it probably won’t happen. And accept it
if it does.
Gun-toting member of audience goes beserk?
• Don’t worry, it probably won’t happen.

What More Can Be Done
More can be done to enhance Amplified Events:
• Photos will be uploaded to closed area of Flickr
for a week, before photos made public
• Learning from experiences on live chat, back
channels, etc. at events
• Managing the physical space – noisy typists and
geeks to left of lecture theatres (where power
sockets are located)
• Understanding our own personal preferences to
avoid information overload:
• Taking responsibilities: mastering applications;
knowing how to disable sound on laptops; how to
configure WiFi; …

Some questions:
• Which Web

winner?
• What should we
make of purple?
• How should we
respond to such
consideration?

Web 2.0
Challenges of Web 2.0
What Is Web 2.0?
Marketing term (derived from observing 'patterns') rather
than technical standards - “an attitude not a technology”
Web2MemeMap, Tim O’Reilly,
20 2005
Characteristics Of Web 2.0
• Network as platform
• Always beta
• Clean URIs
• Remix and mash-ups
 Syndication (RSS)
• Architecture of participation
 Blogs & Wikis
 Social networking
 Social tagging
(folksonomies)
• Trust and openness

Sustainability Problems
Web 2.0
• It’s another bubble
• The companies aren’t sustainable
Initial Response
What’s the odd one out:
• UMIST
• Lotus
• WebCT

Sustainability Problems
Web 2.0
• It’s another bubble
• The companies aren’t sustainable
Initial Response
What’s the odd one out:
• UMIST
• Lotus
• WebCT
• Yahoo!
Answer:
• UMIST was taken over by Manchester University
• Lotus was taken over by IBM
• WebCT as taken over by Blackboard
• Yahoo! hasn’t been taken over (yet)
Lesson: IT companies and public sector institutions may
also not be sustainable. This is not a new issues
Network as Platform

Slideshare Example
I use Slideshare to (a) maximise exposure to my ideas
(b) solicit feedback (c) allow content to be easily
embedded elsewhere and (d) measure impact
Note evidence
which shows
impact of
presentation.
This wouldn’t
have happened
otherwise
Slideshare Example (2)
What happens if
Slideshare goes down –
and it has happened!
Does this demonstrate
that you can’t trust
externally-hosted
services?

Slideshare Example (2)
What happens if
Slideshare goes down –

Does this demonstrate
that you can’t trust
externally-hosted
services?
But local services also go
down – as this example
from the Open University
shows

Performance Problems
It’s not just Slideshare & the OU:
downtime, DOS attacks, … can
happen to all services
We need to understand reasons why:
• Skype unavailable (Microsoft OS
upgrades)
• BUCS air conditioning failure
And explore ways of (a) identifying
problems and (b) minimising risks
Can we really think that problems will only happen ‘out
there’ and that our servers will be available 24x7x365?

spotting potentially
flaky services?

Answers
They are all popular
We can regard them all as destinations rather than a
part of a workflow
The data can:
• Be created there & not be usable elsewhere
• Be created elsewhere and views there

34
Accessibility and Web 2.0
Common response “It’s AJAX; it’s inaccessible”
But:
• Is this using accessibility as a way of stifling change?
• Is assertion backed up by evidence?
• Is it using WCAG 1.0 as ‘evidence’ of inaccessibility?
Note:
• Acceptance of failures of WCAG 1.0 to response to
innovation by WAI staff
• WGAG 2.0 and ARIA
W4A 2008 paper on “One World, One Web .. But Great
Diversity”
• Facebook as tool which users may choose (PLE)
• Not providing podcasts may be the inaccessible option
Network as Platform
35
Avoiding Walled Gardens
The dichotomy:
• Don’t use Facebook, it’s a walled-garden
• Don’t use Slideshare, you might lose your
data
• Do use Facebook and Slideshare, it’s
where the users are & they seem to like it
A resolution:
• Have master copy in managed and
reusable environment
• Use remote service as an interface
(possibly part of a user’s PLE or PRE)
• Provide user education
Network as Platform
Slideshare Example
I use Slideshare to (a) maximise exposure to my ideas
(b) solicit feedback (c) allow content to be easily
embedded elsewhere and (d) measure impact
Note:
• Slides can be
downloaded
• URI for master
provided on slide
& in the metadata
• Accessibility
benefits

Openness and Trust
Inappropriate User Content
Spam
Akismet has protected your site
from 195,127 spam comments.
Potential problems:
• Spam: comment
spam, link spam,
twitter follower spam,
tag spam, …
• Flame wars
• Illegal comments
• Rude words
• Uploading of
pornography, etc
My blog: initially lots of spam comment - but most stopped by
Akismet spam filter. And now only handful posted overnight
37
Openness and Trust
Uploading Dodgy Content
http://connect.educause.edu/blog/
38
Twitterers noticed:
• Porn videos posted
to Educause blog
on Sun 20 April 
• Deleted a few hours
later 
Thoughts:
• Would email be
allowed if released
today? (most email
is spam).
• Need for rapid
response to
problems
Openness and Trust
39
Information Overload
What if we’re too open, sharing
everything?
What if we’re too trusting,
thinking every tweet is valuable?
Need for:
• Better understanding of role
of tools, managing them, etc.
• Confidence to ‘throw things
away’
Surely this is nothing new?
Network as Platform
40
The Fundamental Question
Big question for future isn’t whether we provide blogs,
wikis, etc but how they are provided.
Do we:
1. Build alternatives to Slideshare, YouTube, etc, inhouse. We can be more responsive, we care
about our users and we’re more reliable!
2. Just use the remote services – they’re better,
more functional; and Web 2.0 sceptics are
typically just looking after their own jobs!
What do you think?
Which view are you more closely aligned with?
Network as Platform
41
A Blended Approach
We need:
• Both approaches
• Information literacy (new media literacy,
transliteracy)
• Clearer understanding of our purposes
• Sharing of experiences – successes & failures
• Risk assessment and risk management
strategies
• Application of risk approaches to in-house
services
• …
Embracing 3rd Party Services
What will happen when student
leave (as they do)?
Casey Leaver has documented
experiences in migrating her
blog from Warwick:
• The blog has been delete
• Not all data could be migrated
(pictures & comments are
also lost)
Thoughts: institutional blogs
aimed at staff; support provided
for students using 3rd party
blogs

Deployment Challenges
The Challenges
Areas of concern:
Institutional inertia, vested interests, power
struggles, …
 Applicable for any significant change
Sustainability, reliability, interoperability
 The technical challenges
Privacy, copyright, …
 The ethical challenges
Finding time, finding resources, expertise, …
 The deployment challenges
See “Web 2.0: Addressing the Barriers to Implementation in a
Library Context” for example of barriers in a Library context
43
Deployment Challenges
44
Addressing The Concerns
Some approaches to addressing these
concerns:
• Risk assessment
• Data migration
• Being user-focussed
• Institutional transformation
• Working collaboratively
• Guidelines for use of social networking
services (e.g. Facebook)
Risk Assessment (1)
Risk
Assessment
Management
Loss of service (e.g.
company bankrupt,
closed down, ...)
Implications of sudden or
gradual loss of service
Use for non-critical
services; have
alternatives available ...
Data loss
Likelihood of data loss.
lack of export capabilities
Non-critical use; testing
of export, ....
Performance
problems or
unreliable service
Automated monitoring
…
Lack of
interoperability
User education

Risks Revisited
Are these risks scary?
Remember to include:
• Risks of doing nothing
• Risks associated with
using existing services
Case Study
Open Source Software
can also fail to be
sustainable. The
ROADS software was
developed in UK to
support academic
subject gateways – but
is now no longer
supported.

party wiki the
data is copied

environment
50
Deployment Challenges
51
Personal Audit
Personal audit:
• There’s a need for responsible Web 2.0
enthusiasts to carry out their own risk audit
Departmental audit:
• There’s a need for own risk audits for
services used by others (cf. my events)
Institutional audit:
• Should institutions (& funders) require selfassessment audits to protect their
investment?
Conclusions
To conclude:
• E-Learning 2.0 and Web 2.0 are here and
won’t go away
• Institutions need to engage with Web 2.0
• There are many issues which need to be
addressed
• Solutions are available
• Probably the most important is
collaborative working with one’s peers
