The document discusses Web 2.0 as a concept characterized by user-generated content, social networking, and a shift in web interaction models, rather than a fixed technological definition. It highlights the implications of Web 2.0 for design, business, and user experience, while cautioning against excessive hype and the lack of a simple definition. Additionally, it identifies ten issues facing Web 2.0 today and presents examples of applications that embody its principles.

1. Web2.0: Second coming or Sound and Fury?
20 April 2006

2. Tomorrow, and tomorrow, and tomorrow
Creeps in this petty pace from day to day,
To the last syllable of recorded time
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
-- MacBeth V.v.

Web2.0: Miscellaneous definitions
> “The Web as Platform”
– Tim O’Reilly
> “The Web as Platform for __________”
– Richard McManus
> “Web2.0 means using the Web the way it’s meant to be used. The
‘trends’ we’re seeing now are simply the inherent nature of the
Web emerging from under the broken models that got imposed on it
during the Bubble.”
– Paul Graham
> “Web2.0 is where [the seeds of new and interesting technologies]
take root in the soil of business.”
– John Battelle

7. 7
Web2.0: Miscellaneous definitions (cont’d)
> “Like many important concepts, Web 2.0 doesn't have a hard
boundary, but rather, a gravitational core. You can visualize Web 2.0
as a set of principles and practices that tie together a veritable
solar system of sites that demonstrate some or all of those
principles, at a varying distance from that core.”
– Tim O’Reilly
> “Web2.0 is a marker of the reinvigoration of competition more than
technology.”
– Danah Boyd

13. 13
Web2.0 lies at the crossroads of many trends

14. 14
Web2.0 might be...*
> about Web applications and services
> supported by a collection of (previously existing) technologies
> a collective feeling that something is changing and growing in how
the Internet is used
> an indicator of broader social and business trends
> surrounded by a lot of hype
> obsessive navel-gazing by a small group of people
> consistent with trends in previous technological innovations
> a stepping stone
* in my opinion

15. 15
Web2.0 is NOT...
> the second coming
> strictly a matter of technology
> meaningful in the sense of software version numbers
> something every company absolutely has to pick up and use
> the future of the Web
> a clearly defined service offering or application “space”

Example by deconstruction

Folksonomy: Taxonomy for the Masses
> “Given enough eyeballs, all bugs are shallow.”
– Eric Raymond, paraphrasing Linus Torvalds, creator of Linux

29. 29
But is it useful? The debate rages on...
> Folksonomists: “the death of taxonomy” (Tim O’Reilly), “ontology is
overrated” (Clay Shirky)
> Others: “hyperbole” and “apophenia” (Peter Morville)
> Exemplifies a broader Web2.0 debate,

44. Implications for Web design

45. 45
Implications for Web design
> Web experience design is changing
> Shift away from page-based interaction models is significant
> We may need new approaches to how we review and present our
work to clients
> We may need to rethink the design process for some projects (i.e.,
potentially explore XP-style rapid, iterative development cycles
with interactive prototyping)

46. 46
Implications for Web design (cont’d)
> Impact will be felt in many different areas
> Strategy: Understanding of trends and how they impact the content, services, and
products delivered by companies
> Interaction design: Evolution of Web interaction models; new ways of wireframing?
New ways of presenting interaction approaches? Greater need for understanding of
technology
> Editorial: Vocabulary for services and tools; Ability to articulate how the Brave New
Web World enhances customer experiences; Insight into broader universe of user-
generated content (and its pitfalls)
> Graphic design: Trend (push?) in many sectors towards highly simplified visual designs
focused on high information density, minimal graphic elements
> Technology: Greater demands on developers; impact on testing; cross-platform
implementation challenges

47. 47
Implications for Identity design and Brand building
> No direct implications for the visual expression of brand identity
> Large implications for how companies interact with their
consumers (e.g., business models for content and services)
> Could lead to the downfall of many traditional business models
(e.g., packaged software for some products)
> We need to think through the implications of “Web2.0” for our
clients – before they do

48. Broader implications

49. 49
Roadkill on the Web2.0 megahighway

50. 50
Oh, what a tangled Web we’ve woven!
> Are we burying ourselves in complexity?
> We can’t filter the infoverse without our technologies
> Whose truth is it, anyway?
> Things are dynamic, but are they durable?
> Emergent properties are still hidden

51. Summary and resources

52. 52
Summary
> Web2.0 is a concept, not a concrete thing
> Avoid the term (if you can); avoid the hype
> Trends cross many different domains
> Deep implications for user-centered design, usability, and design
processes
