Local Wikipedia — a project posted at edjefferson.com under the tagline “Wikipedia, but only for things a half hour walk from you” — spent this week at the top of Hacker News with 1,509 points and 240 comments. I cannot tell you what is inside it. Neither, I’d wager, can most of the people who upvoted it. The tagline is doing all the work, which is precisely what makes it worth arguing with. The idea got the points. The idea always gets the points.
Here is what the idea is, stripped of its charm: proximity as an epistemic credential. The assumption that because a thing happened within a mile and a half of your kitchen, the account of it written by people who also live within a mile and a half is somehow more trustworthy than the account written by strangers.
It is the reverse, and the reasons are structural.
Wikipedia’s Achievement Was Independence, Not Participation
The thing everyone remembers about Wikipedia is that anybody can edit it. The thing that actually made it work is the rule underneath: a subject earns an article when it has received significant coverage in reliable sources independent of the subject. Independent is the load-bearing word, and it is a word about the author, not the topic.
A half-hour radius selects for the opposite of independence. It selects for standing. Half an hour’s walk is roughly a mile and a half, and inside that circle sit your landlord’s other buildings, the restaurant owned by your neighbor’s brother-in-law, the pothole the councilman’s cousin keeps promising to fix. Every one of those is a legitimate subject for an encyclopedia. Every one of the people positioned to write the entry has a reason not to.
Wikipedia worked because it drafted strangers — people who would never meet the subject, never eat at its restaurant, never run into its owner at the hardware store on a Saturday. That is not a bug in the cosmopolitan model. It is the whole machine.
The Local Record Is the Most Captured Record We Have
The romance of hyperlocal knowledge rests on a story about the death of the town paper, and the story is wrong in an instructive way. Local journalism did not fail because it was too distant from its subjects. It failed, in many markets, because it was too close — dependent on the advertisers it covered, friendly with the officials it was meant to watch, unwilling to be rude at the funerals.
The distance problem and the capture problem are different problems, and the second one is worse. A reporter flown in from three states away gets the zoning code wrong but has no incentive to protect anybody. A reporter who lives four blocks from the contested development has the zoning code memorized and a kid in the school that the developer promised to fund.
I put this to a county recorder’s clerk in southern Illinois one afternoon, while she stamped deeds and made clear she had better things to do. “Everybody in this building knows whose name is on every parcel in this county,” she said. “That’s the problem. You want the truth about a piece of land, you ask somebody who lives two counties over and has to look it up.”
She was not being cynical. She was describing an information system.
Subsidiarity Is a Rule About Power, Not About Truth
This is where my own side should start squirming. Conservatives have spent a generation defending local control, and we have been right to, but we have conflated two arguments that need to be kept apart.
The case for subsidiarity is procedural: local decisions are accountable, reversible, and exitable. You can show up at the meeting. You can move three towns over. You cannot do either to a federal agency. That is a real and sufficient defense of federalism, and it does not require the locals to be correct about anything.
The moment you tell yourself that proximity also makes them right, you have handed the school board jurisdiction over what the water tests say. You have turned a procedural preference into an epistemology, and the epistemology is bad. The 240 comments under item 50202285 are worth skimming for how quickly the conversation slides from “this is charming” to “this is how we take back the record from the people who’ve been writing it.” Take it back to whom, exactly? The people with the most to lose.
Keep the Strangers in the Room
None of this means the project is worthless. It means the radius belongs in the discovery layer, not the credential layer.
A local wiki that surfaces the subjects worth writing about — the rezoning on your block, the bike lane nobody announced, the building that changed hands six times in four years — would be genuinely useful, because the biggest gap in the public record is not accuracy, it’s attention. Nobody is writing the entry at all. Fixing that is a real contribution.
The moment you write it, though, you need someone in the room who cannot be at the next council meeting. A standing-disclosure field would do more for this project’s credibility than any radius. An article about the corner where the city is putting in a bike lane should have at least one author who has never ridden past it.
A half-hour walk tells you where a claim lives. It tells you nothing about whether it’s true. That distinction used to be the entire business of an encyclopedia, and it is the one thing a tagline this good will never supply.
