The document discusses the evolution of Web 2.0, highlighting the importance of community and user contributions in creating value and fostering interaction. It emphasizes concepts such as cumulative advantage, network effects, and participatory architecture, suggesting that successful contributions can encourage further participation. Overall, it outlines strategies for harnessing collective intelligence and designing flexible applications that enhance community engagement.

2. eschew mentalistic
explanations
you tend not to get
caught up in them
when working with
preverbal animals

3. Internet Trolls: are shy
people who engage in
argumentation to fulfill their
need for conversation and
human contact.
Really? How do you know?

Network effects from user contributions are the
key to market dominance in the Web 2.0 era.

12. What is the story about?
Multiplying a scarce resource via community
This is an economic tale
The community was altered
The rules of exchange were altered
Changed the Economy
community = economy

13. So far...
Jamie is an economist in disguise
Stone Soup is an economic tale
Community is another word for economy

19. Methylene Blue, methylthionine chloride or 3,7-
bis(dimethylamino)phenothiazin-5-ium chloride, with a
molecular formula of C16H18ClN3S, is a dye and medication
used in Gram's stain, Wright stain, and the treatment of
metoxyhemoglobinemia.
Its CAS number is 61-73-4: its EC number is 200-515-2 .

20. Pyramids of Contribution Opportunities
Community at any scale.
Not just one pyramid.
Each Pyramid of contribution fosters many others.

23. Users will create/fill-in
missing mechanisms. Can
we capture/extend their
work (to take advantage of
the data they are creating.)

24. Branch/Merge well know to technical community - how do
we extend to the broader community?

25. Need to understand the structure of
the conversation to analyze it.

...modular architecture that allows easy
participation by independent or loosely
coordinated developers.

have to look

clocks were 24

Cumulative Advantage?

56. The rich get richer
and
Connected data attracts more connections

57. The foundation behind:
-Scale Free Networks
-Small World Networks

58. "If you need scale in order to create value, it's hard
to get scale, because there's little incentive for the
first people to use the product. Ideally, the system
should be useful for user number one."
-Joshua Schachter, 2006

59. Old - but still filled
with great ideas!

60. Dan Bricklin:
Cornucopia of the Commons
• Three ways to build a database
• Organize manually
• Organize mechanically
• Get volunteers to build it

61. "...one can predict the success of a particular
system for building a shared database by how much
the database is aided through normal, selfish use."
-Dan Bricklin, 2001

64. Stone Soup Review
Multiplying a scarce resource via community
Cumulative Advantage:
-once people started to contribute....easier
for others to contribute....positive feedback.
Architecture for Participation:
Cumulative advantage - loosely coupled.
- If one contribution failed, others could
succeed.
Architecture for participation Community at all scales:
-Different type of contribution
Community at all scales -Individual contributions,
-family contributions,
-pre cooked contributions
-community contributions

65. ‣Think about data accumulation in interaction design
‣Design for Network Effects
-Allow community to work at all scales
-Provide tools for bifurcation management
-Facilitate Percolation (but don't over connect)
-Couple contributions loosely
-Foster Group Forming Networks (2 N scaling)
-Guide data convergence through vocabulary
-Leverage cumulative advantage
‣Deliver value, create data, deliver value
