Journalism was the input. Gravity was the product.
Journalism was the input. Gravity was the product.
For most of the last century the local newspaper was a city’s binding agent. It gave residents a common set of things to know and talk about, and in doing so it held otherwise unrelated parts of a city in contact with one another. That function has largely disappeared, and what replaced it is national by design. The attention a city once spent on itself is now spent elsewhere.
Cityverse is a way to rebind a city. It is being built first in St. Petersburg, Florida.
What a city lost
A city of two hundred thousand people once shared one object every morning. The newspaper told a mechanic and a bank president the same forty facts before either of them got to work. It printed the school board agenda and the high school box scores and the obituaries and the zoning notices, and gave a quarter million strangers a common set of building blocks for constructing their days.
Ask someone what they lost and they will not say oversight. They will say they no longer know what is happening this weekend. They do not hear about the new restaurant until it has been open four months. They do not know that a neighbor two streets over died.
An advertiser buying a half page in 1985 was buying one thing: the fact that most of the city would read the same object on the same morning. The paper spent money producing something a town would gather around, then sold access to the gathering. When the business moved online, publishers behaved as though the journalism had been the product. They put it behind paywalls and cut the calendar, the classifieds, the club notices and the obituaries, which were among the strongest gravity the paper had.
Gravity is a city’s attention, assembled in one place, in a form that local parties can act on. A resident who spends ninety minutes a day inside a national feed is engaged and unreachable at the same time.
That trade is still available, and the tools for it are better than a printing press ever was: cheaper, more numerous, and adjustable. Gravity can now be built deliberately, out of many small pieces rather than one daily edition, and building it produces civic goods along the way.
The design in ten sentences
Each sentence is defended in the chapter it names. A reader who remembers only these has the design.
Journalism was the input. Gravity was the product.
Value is created where it cannot be captured, so the links that would carry it are never built. Build them anyway.
A chain needs three links: a producer who cannot capture, a transformer, and a captor who funds the producer. Two links is a marketplace.
Exactly one link is bought. Every link after it is free.
Costs land on the feature and revenue lands on the network. Never judge an instrument by its own ledger.
A link may live in someone else’s building if the bond at the boundary holds after the people change.
Nothing is priced at the door. Inside the membership, ordinary pricing applies.
Reading is open to the world. Participating requires living there.
Moderate the civility of an exchange and leave the idea alone.
Each city’s record stays its own, and the valve on what leaves it stays in the city’s hand.

A Design for Rebinding American Cities
The paper
Part One makes the argument, complete in four chapters: what a city lost, what a newspaper actually sold, one value chain end to end, and how to tell a chain that will run from one that will not.
Part Two is the design in detail, and its chapters can be read in any order: the bought link, how gravity pays, chains that cross buildings, where the price sits, who gets in, free food, consent, two frogs, the faucet, what this does not solve, and the chain factory.
This is the first of a series. Three further papers are in preparation.

Cityverse is the design, built
Building a city’s attention deliberately produces civic goods along the way: local coverage, a market for local work, tools that institutions could not afford alone, and a place where residents meet as neighbors. The figures below show the product in four layers. Four surfaces every resident uses; two ways a city is kind to itself in public; three examples of tools that live inside other people’s buildings; and three of the features that pull attention home.
Figures 1 to 4 are the working designs for St. Petersburg. Figures 5 to 12 are illustrations of the idea, drawn in the same system.
The surfaces
Four places a resident is, in a day. Each is a piece of the one object a city used to share every morning, rebuilt so it can be assembled from many hands instead of one newsroom.
Community, and positive drama
National feeds run on conflict because conflict travels. A city’s feed can run on something else. Two features built so that the most shareable thing in town is a kindness.
Tools in the chain
Costs land on the feature and revenue lands on the network. So the network can give away software an institution could not afford alone, and a league, a gallery or a realtor becomes a link that brings its own people with it. Three examples.
What pulls attention home
The classifieds, the calendar and the personals were the strongest gravity a newspaper had, and the first things publishers cut. Rebuilt for a membership of verified residents, they are the reasons a person opens the city every day.
Every city is its own biome
A frog in Madagascar and a frog in Peru are both frogs. One can kill you; one may hold a compound that cures something. Nothing in the general category tells you which, because the answer is a property of the biome. Two American cities of the same size will answer the same zoning proposal in completely different ways, for reasons that live in local history and a hundred fights that happened before anyone in the room arrived.
So each city runs its own Cityverse. Its record is built from its own data and stays its own. Reading is open to the world; participating requires living there.
Built on the St. Pete Catalyst’s audience and newsroom.
How a second city gets built is chapter fifteen, the chain factory.
Operators
Cityverse is built by the team behind the St. Pete Catalyst, an independent local news operation in St. Petersburg, Florida. The white paper describes a trade the Catalyst has been running for years. Cityverse is that trade built deliberately, with the pieces a printing press never had.
