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.

What is the story about?
Multiplying a scarce resource via community
This is an economic taleThe community was alteredThe rules of exchange were alteredChanged the Economy
community = economy

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

"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."

Stone Soup Review
Cumulative advantage
Architecture for participation
Community at all scales
Cumulative Advantage:-once people started to contribute....easier for others to contribute....positive feedback.
Architecture for Participation:- loosely coupled. - If one contribution failed, others could succeed.
Community at all scales:-Different type of contribution-Individual contributions, -family contributions, -pre cooked contributions-community contributions
Multiplying a scarce resource via community
![Page 65: The next phase of Web2.0: Data](https://reader033.vdocuments.us/reader033/viewer/2022052820/5492f7a4b47959604d8b470c/html5/thumbnails/65.jpg)
‣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 (2N scaling)
-Guide data convergence through vocabulary
-Leverage cumulative advantage
‣Deliver value, create data, deliver value
