Public goods exist in part because, per Mansur Olson's logic of collective action, if they were privately provisioned at scale everyone has an incentive to opt out (free-ride), so they get under-created in purely voluntary arrangements—this is the flip side of the birthday paradox's network economics.

Markets exist (rather than organizations) where the level of transactions and the complexity of interacting actors are both large enough that you cannot coordinate within an organization—famously what 'did in communism' at the end of the last century.

Organizations exist to lower transaction costs: Coase observed that if markets are so efficient, the reason we have firms is that pricing and contracting for every small transaction (like buying pencils) would swamp the institution's ability to accomplish larger goals, so firms internalize those transactions.

Lowering transaction costs becomes a side effect of using networked tools (internet, mobile phones, apps): finding people with shared or complementary interests and coordinating with them becomes far easier, mirroring how search and e-commerce eased commercial transactions—enabling a 'ladder' of sharing, collaboration, and collective action.

Beyond Coase's well-known 'ceiling' (where firms stop being efficient and markets take over), there is a neglected 'Coasean floor': a set of valuable transactions that no one engages in because they require organization, yet no organization will undertake them because the transaction costs are too high relative to any extractable profit.

Maintaining an institution capable of lowering transaction costs itself creates costs (e.g. middle management as the overhead of coordinating large organizations), which is why some valuable activities remain below the Coasean floor.

Flickr's aggregation of 3,000+ Mermaid Parade photos via freeform tagging accomplished something no institution could do: it created large-scale social value as a side effect of self-interested individual actions, without advertising costs, coordination, or any profit motive—because the value existed but was insufficient to overcome the transaction costs of for-profit assembly.

Networked communication fuses the previously distinct modes of broadcast and personal communication into a single channel, so content can scale effortlessly from private to public—meaning something no longer has to be interesting to more than two people to be worth putting online, a shift that disorients people raised in the prior broadcast/communication divide.

The birthday paradox illustrates that social complexity scales with the number of pairwise connections, which grows with the square of the number of participants, not linearly—so 36 people yield over an 80% chance of a shared birthday; this is why large organizations are qualitatively different from small ones and must be run differently.

Coordinating preferences across a group grows combinatorially: getting ten friends to agree on a movie requires forty-five pairwise preference comparisons, so beyond a small scale groups must adopt formal mechanisms (voting) or unilateral governance ('I'm going to this movie, join if you want')—not because of human malice but because it is the only way to manage large groups in institutional settings.

The web privileges effectiveness over efficiency, allowing organized behavior at scales impossible to manage institutionally: Wikipedia's editorial culture (~2 million English contributors, ~5 million across languages) is roughly 100,000 times larger than its managerial culture—an inversion of a newspaper, where the managerial culture (all employees) is about twice the editorial culture.

When we observe organized behavior we wrongly assume an organization is directing it, but phenomena like Wikipedia pages are organized without an organizer—an instance of what Hayek called emergent order.

Working direct democracies (Swiss cantons, New England town meetings) are bounded by scale: past a certain size the transaction costs of participation become prohibitive, so beyond that scale representative democracy is required—but networked tools now make it possible to experiment with hybrid forms that more directly assess public preferences without relying solely on periodic elections.

Majority voting can manufacture an illusory 'will of the group': if six prefer a gory action film and four prefer a romantic comedy, declaring the action film the group's will misrepresents preferences, so where collective action is not strictly required, such decisions should be removed from the political marketplace and decoupled in a live-and-let-live way consistent with liberty.

Words and reading are becoming less important while images, skimming, and browsing become more important, evidenced by the scale of image platforms (Flickr ~2-3 billion images, Facebook over 5 billion)—a largely unnoticed social phenomenon enabled by bandwidth and access.

The internet turbocharges homeschooling: contrary to the stereotype that homeschoolers withdraw into isolation, they form deep networks—sharing educational materials, advice, and even a used-textbook market that exists only within the homeschooling network—reproducing the economics of public goods (infrastructure previously only provisionable by the state) without state provision.

We are witnessing 'the end of cyberspace'—the idea that the internet is a separate alternative space one retires into is being replaced by people using the internet to augment real-world activities, including coordinating face-to-face meetups.

Many criticisms aimed at the internet (alienation, passivity, social decay) are misdirected—they actually describe the culture created by television, a battle 'fought and lost by the 1960s'; people are now reading and writing more than before, and doing some of their ~20+ hours/week of screen time with a keyboard and mouse rather than passively, which is hardly a calamity.

Per Danah Boyd's research, the rise in teenagers' social-network use correlates with a reduction in their freedom to go outside: parents and authorities increasingly keep teenagers indoors and apart (a 'mass house arrest'), and teens respond by maintaining social lives through the media they're permitted to access.

Nupedia's failure demonstrates that grafting the institutional transaction-cost model onto the web doesn't work: its seven-step expert workflow created seven points of potential stalling, and as a voluntary effort it produced only about a dozen articles in nine months—whereas Wikipedia succeeded by replacing organized process with massive perennial peer review where everything is provisional.

A key reason institutional projects stall is that gatekeepers with veto power enjoy that doing nothing means nothing happens; Wikipedia's success came from NOT giving experts veto power—a deliberately simplistic article ('asphalt: material used to cover roads') triggers others to say 'I can do better,' so articles improve from a provisional seed rather than waiting indefinitely for the ideal expert.

Wiki software shifts the economics of collaboration so that undoing damage is easier than doing it—'imagine it was easier to take spray paint off a brick wall than to put it on'—because radical transparency and full edit histories let any editor reset an article to its last known-good state in a couple of clicks, giving defenders a structural advantage that, for the first time on the internet, favors those who want to preserve value.

Wikipedia's success in lowering transaction costs simultaneously opens it to system-gaming (e.g., editing of the Sarah Palin article before her VP announcement), forcing it to back into governance models (semi-protection, edit-war handling) that balance open participation against abuse—making the Wikimedia Foundation effectively 'the experimental wing of political science.'

Cognitive surplus is the reconception of leisure time—the ~20 hours/week of TV watching per person, aggregating to roughly a trillion hours/year in the industrialized world—as an aggregate raw material that can be designed around; Wikipedia consumed only ~100 million hours total (less than Americans spend watching ads on a single weekend), making such projects explainable as harnessed surplus requiring only invitation and reward rather than recruiting and management.

Economists pre-2000 would have predicted Wikipedia could not work because of the free-rider problem—everyone would happily read it but no one would create it without profit or glory; they were wrong because they misunderstood the pure pleasure (plus small private non-monetary returns like comments and recognition) that overcomes free-riding, making such voluntary contribution a massive positive social externality unprecedented in human history.

Social science explanations of collaborative phenomena must become largely probabilistic ('cloudy with a chance of collaborations') because social life involves many complex feedback loops making it more like predicting weather than gravity—even with full knowledge of inputs, predictability is far lower than the neoclassical model hopes, and such phenomena get stuck in special cases (you couldn't recreate Wikipedia with identical inputs because Wikipedia already exists).

The signal non-technological enabler of harnessing cognitive surplus was the creation of the open-source license (GPL, by Richard Stallman ~25 years prior), which injected 'the right amount of inefficiency' into the IP system—using copyright law to subvert rather than extend copyright's traditional goals by granting more rights to users and fewer to creators, so contributors no longer fear being alienated from their work.

The next breakthrough will be a 'license for collective action' analogous to the GPL: a legal vehicle (like Vermont's experimental virtual company—no paper filings, physical headquarters, or hierarchical management) that lets purely online groups be deferred to by the state to hire, fire, hold bank accounts, and create bylaws, which would explode collaborative activity beyond information production into real-world action.

Federalism enables institutional innovation: because there are 51 decision-makers rather than one, even if a single national decision on virtual companies would likely be 'no,' a single state like Vermont can experiment, and if it gains traction politicians will weigh increased profitability against decreased power and favor profitability—potentially making Vermont 'the Delaware of cyberspace.'

When measuring changes in the American standard of living, we neglect changes in the workplace—in 1900 about 40% of Americans worked on physically dangerous, brutal farms, whereas today's workplace is remarkably safe and, notably, allows much more leisure on the job (people listen to podcasts at work).

Behavioral economics has passed through the first three of Bill Hamilton's four phases of a scientific theory (not true / interesting but perverse / true for edge cases / everyone always knew it), reaching the stage where everyone accepts neoclassical economics fails to explain certain cases (ultimatum and dictator games), but we have not yet seen an interpretation that moves behavioral economics to the center of the calculation rather than the neoclassical model.

Calling Wikipedia a 'positive externality' reveals a theory not working hard enough: the externality of Wikipedia is in fact the business/economic value it creates, while the social effects are internal to the transaction—so internalizing non-financial motivations would better explain what is going on, and Wikipedia will stop being viewed as an externality.

Neoclassical economics is not as naive about altruism as the straw-man critique suggests: economists, including Adam Smith, have long understood Homo economicus is not purely selfish and have studied charity for centuries—the real failing is that the formal models of how much altruistic activity would occur were 'quite sterile,' and embodying non-financial motivation properly in models may be beyond the scope of social science.

Different sciences accept different standards of proof: a biologist accounting for a phenomenon to the 95th percentile celebrates, whereas a physics experiment that is only 95% correct 'is wrong on its face'—implying social science, dealing with complex feedback loops, must accept lower predictability standards.

Existing examples of online collective action are all protest-oriented—relying on 'stop energy,' short-term, high-visibility coming-together to register protest against political or economic entities—rather than groups that come together to take constructive real-world action and succeed or fail as a durable group.

The threshold to learning a craft like photography has fallen from a gap into a spectrum: where improving meant joining photo clubs and subscribing to magazines, the socialization of sharing now exposes everyone to others' photos and lets them ask photographers directly how a shot was taken, lowering the threshold of learning something new.

The aggregate view of shared photos is not merely a post-hoc gathering but actually creates the incentive for more people to take more pictures.

The New York City Council overriding the term-limits law that voters approved twice—reportedly so the mayor can run for a third term, with a quid pro quo letting council members also run again—is a large 'bug' in the representative system, overriding the clearly expressed will of voters simply because they can.

Public goods like garbage collection and schooling are provided publicly to everyone all the time because it is cheaper to do so that way.
