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...
Viral Effects Are Not Network Effects
Virality and network effects are conflated by even experienced Founders, and it keeps them from developing the right strategies and playbooks.

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.

Speeding up code review with `small-change`
Imprint’s average engineer is merging 4x more PRs than 2 years ago. Yay. Aggregated behind the average is something even more interesting: we have two teams that are merging 10x their PRs over that period. One engineer is merging 25x the PRs per week of our average engineer two years ago, and a number of others are closing in on that number. That’s pretty neat, and the slope of the line suggests our average in a year is going to look much closer to today’s p90 than today’s p50. Even more importantly, we aren’t just shipping more, our quality has improved: incidents are down 42% half-over-half, and critical incidents are down 78% half-over-half. I think we’ve always known the quality/velocity tradeoff wasn’t a particularly useful construct, but that’s undeniable today.

Seize the Means of Computation - ProMarket
To regain internet autonomy from Big Tech companies, lower switching costs with legislation that allows new services to subvert network effects and encourage adversarial interoperability. Too often, our discussion of Big Tech’s dominance starts and ends with a simplistic account of network-effects-driven inevitability, as though the winner-take-all market we have today could not have been […]

This started up as a write-up for a cool hack I made (Atproto DID + Tailscale, coming soon 😎), but like many times before it started taking a life of its own, about how an integration of small scale networks is a more sustainable version of "internet scale" than large tech monopoly data centers.
