How big should a peer-to-peer network be before it generates a steady stream of deals?
Estimating peer effects in noisy, low-rank networks via network smoothing
Peer effect estimation requires precise network measurement, yet most empirical networks are noisy, rendering standard estimators inconsistent. To address measurement error in networks, we propose a method to estimate peer effects in networks whose expected adjacency matrix is low-rank. Our key result shows that peer effects over a true unobserved network are asymptotically equivalent to peer effects over the expected adjacency matrix. This result reduces peer effect estimation in noisy networks to low-rank matrix estimation targeting the expected adjacency matrix. We develop our theory for weighted networks observed with additive noise, but simulations suggest approach can be applied more generally when there is a low-rank estimation method suited to a particular noise structure. We demonstrate via simulations that our approach applies to egocentric samples, aggregated relational data, and networks with missing edges, each requiring a different low-rank estimation method.

We’ve all heard of those network effect laws: the value of a network goes up with the square of the number of members. Or the cost of commun...
The Wealth of Networks
The Wealth of Networks: How Social Production Transforms Markets and Freedom is a book by Harvard Law School professor Yochai Benkler published by Yale University Press on April 3, 2006. The book has been recognized as one of the most influential works of its time concerning the rise and impact of the Internet on the society, particularly in the sphere of economics. It also helped popularize the term Benkler coined few years earlier, the commons-based peer production (CBPP).
Why isn't Bluesky a peer-to-peer network?
Today in "our novel form of NIH," why did Bluesky choose not to use a peer-to-peer network when designing the AT Protocol?

Open Source infrastructure deserves a business model
Open Source infrastructure is essential, invisible, and chronically underfunded. A more sustainable approach may be to connect the cost of running that infrastructure to the organizations that rely on it most.

A conceptual model of ATProto and ActivityPub
If you were to design an open social networking protocol, what would that look like? Which metaphors and comparisons would you use to get a general idea of how the network functions? And what would you answer if people ask if your network is decentralised and federated?

We need better ways to sell people on decentralization, AT Protocol, and Bluesky than telling them open networks mean they won't have to suffer through losing yet another platform to an Elon Musk.
Decentralization is Insurance
www.aaronrosspowell.comfull-network space efficiency update: bad news: event though 84% of all repos are stale (no activity in 30 days), stale repos only make up 20% of the data in the network. moving them to cheap storage doesn't buy much. good news: the data in network is small?? like sub-1TB, minimal magic needed
