I'll pay the bills. Period.

I'll do admin if needed (software updates and the like). But you decide what kind of community you want it to be, so you put together the mod team.

On the Architectural Hostility of Doorknobs Before we begin, I am in the USA, where levers are rare. Most people think of doorknobs as simple things. A bit of metal, maybe some ceramic or glass, bolted to a slab of wood. A mechanism. You turn it, a latch retracts, a path opens. Simple. It’s a transaction so mundane it evaporates from memory the instant it’s complete. You perform this minor mechanical miracle dozens of times a day and think nothing of it. But you have the luxury of sight. For me, a doorknob is never just a doorknob. It’s the first handshake with a room. It’s the opening sentence of a building’s story. It is a dense, information-rich object, a metal or porcelain palm that tells me everything I need to know about the space I am about to enter and the people who inhabit it. It’s a tactile bellwether for empathy, consideration, and sometimes, for danger. It is the gatekeeper, the greeter, and the warning sign, all in one. Show me your doorknobs, and I’ll tell you who you are. Let us begin with the angels of the door-opening world: the lever. God, I love a lever. The long, elegant bar of a well-designed handle is a thing of pure, functional beauty. My fingers close around it, and there is no ambiguity. There is a clear direction of force. Down. It moves with a clean, decisive _clack_ , a satisfying mechanical surety. A lever is a promise kept. It says, "I was designed by someone who considered that a hand might not be empty. I was designed by someone who thought of the woman with groceries, the father carrying a sleeping child, the person with arthritis whose knuckles ache at the very thought of a twist." A lever handle says, "You are welcome here, and your journey into this space will begin without a fight." It speaks of accessibility, not as an afterthought or a begrudging concession to a building code, but as a foundational principle of hospitality. You find these paragons in thoughtful places: modern libraries, community centers run by people who actually care, the homes of friends who are occupational therapists. Their presence signals a quiet competence, a subtle declaration that the architecture of this place is on your side. My hand meets the lever, and my shoulders relax a fraction of an inch before the door even opens. The first handshake was firm, confident, and kind. I trust this place already. And then, there is its antithesis. Its nemesis. The perfectly round, perfectly smooth, perfectly polished brass sphere of pure malice. You know the one. You’ve fought this battle, too, even if you could see the damned thing. It gleams under the light, a tiny, smug planet of impossibility. My fingers, perhaps slightly damp from walking in the rain or just from the low-grade anxiety of navigating an unfamiliar building, slide across its frictionless surface. There is no purchase. No edge. No hint of which way to torque this crystal ball of inconvenience. This is not a handshake; it is an interrogation. My hand cramps. I try to create friction with my palm, pressing my full weight into it as if trying to physically intimidate the door into opening. I begin the Doorknob Cha-Cha, a pathetic dance of desperation known only to those who have faced this particular foe. One hand holds my cane, tucked awkwardly under my arm. The other is contorting, my wrist bent at an angle that would make a yoga instructor wince. I'm trying to grip a sphere. A _sphere_. The most fundamentally un-grippable shape in all of geometry, and some sadist in the 1890s decided it would be the perfect object to operate a door. This knob tells me a different story. It tells me that this building, this room, was designed with an idealized, able-bodied ghost in mind. It was designed for someone with dry, strong hands and no distractions. It was designed for tradition over function. It screams, "We have always done it this way, and we have never once stopped to ask if 'this way' is monumentally stupid." It’s the doorknob of historical homes turned into frustrating B&Bs, of old university buildings that value aesthetic over people, of government offices that are functionally designed to wear you down before you even get to the counter. It is architectural hostility in its purest, most benignly evil form. It is a small, round, metal middle finger to anyone who deviates from a non-existent norm. It’s funny, in a way. A cosmic joke told by an interior designer with a dark sense of humor. I stand there, wrestling with this orb, and I can almost hear the house laughing. But not all doorknobs are jokes. Some are ghosts. Some are scars. The doorknob of my childhood was cold. Not just the physical cold of brass in a poorly heated hallway, but a deep, permanent, soul-level cold. It was an ornate, Victorian thing, heavy and unforgiving. It never warmed to my touch. My small hand would close around it, and the metal seemed to actively leach the heat from my skin. It had a specific, grating squeak as it turned, a sound that always felt like a sigh of reluctance. It was the sound of permission being granted, but never offered freely. That doorknob was the perfect metaphor for the house itself. It was a formal, unyielding barrier. You didn't casually pass through it; you made a formal request. Its coldness was the coldness of a space where affection was conditional and my needs were a constant, low-grade inconvenience. The sheer weight of it, the effort it took for me as a child to turn, felt like a daily reminder of my own inadequacy. The world inside that door was one of quiet, brittle tension, of navigating emotional minefields by sound and tone alone, and the doorknob was its stoic, unfeeling guard. It never changed. Year after year, my hand grew, but the knob stayed just as cold, just as resistant. It told a story of rigidity, of emotional distance, of a home that was a structure but never a sanctuary. It taught me that the first touch can tell you if you’re about to enter a place of warmth or a place where you will have to brace yourself. I learned that lesson again, more brutally, later on. There was another door. Another knob. This one was cheap. You can feel "cheap" in a doorknob. It’s a hollowness. A looseness in the mechanism. This one was a builder-grade brass-plated tulip shape, the kind that comes in plastic wrap at a big-box hardware store. It was flimsy and slightly wobbly on its spindle. It didn't have the honest, solid resistance of my childhood home's knob. It had a sickly, unreliable give. The memory of it lives in my hand, not my head. My hand remembers the specific way it would stick, requiring an extra, violent twist to unlatch. My hand remembers the slight jagged edge on the shank where the plating had worn away, a tiny sharpness that was always there, a little promise of pain. My hand remembers the jiggle. The sound of his key in the lock, followed by that loose, rattling turn of the knob. That sound. Even now, years later, a similar sound can make the world fall out from under me. It’s a full-body response. The bottom drops out of my stomach. The air in my lungs turns to ice. Anxiety, which for me is often a swarm of loud elephants under my ribs, becomes a frantic, roaring vortex. That wobbly, cheap doorknob was the herald of my own personal apocalypse. It was the first touchpoint of a cage. Turning it from the inside to leave felt like trying to lift a mountain. Turning it from the outside to enter, knowing he was there, was an act of self-annihilation. He knew I hated it. He knew the sound it made was a trigger. Sometimes, he’d just stand on the other side, jiggling it. Slowly. Deliberately. Just to watch me flinch. An object of passage became an instrument of psychological torture. That doorknob tells the darkest story of all. It speaks of the veneer of normalcy hiding something rotten. It speaks of neglect—not just the neglect of a landlord who won't fix a cheap fixture, but the profound, systemic neglect of a person's soul. It feels of betrayal. It tastes like fear. Show me your doorknobs. That one showed me a monster. It’s a miracle I ever trusted a door again. It takes a long time to unlearn that kind of lesson. It takes a long time to believe that a door can be anything other than a barrier or a trap. You begin to see the world through this lens. You go to a job interview and the door to the office has a sleek, heavy, brushed-steel handle. It feels impressive, but also impersonal. Cold in a different way. The knob of corporate ambition. It feels efficient and unforgiving. It says, "We are all replaceable cogs in this machine, including you." It speaks of profit margins and productivity, not people. You go to a government agency, a place of supposed public service, and the doorknob is loose, grimy, covered in the faint, sticky residue of a thousand desperate hands. It feels of institutional exhaustion. It tells a story of budget cuts and apathy. It sighs, "Take a number. We'll get to you when we get to you. Or maybe we won't." It’s the knob of bureaucracy, and it feels like giving up. Each one is a story. A biography of a space, written in metal. The fragile, crystalline knob of a grandmother’s bedroom, a handle you touch with reverence, feeling the history in its delicate facets. It smells faintly of lavender and dust, and speaks of a life carefully lived. The sticky, plastic-handled knob of a back door to a favorite coffee shop, a knob that feels like community and smells like burnt sugar and roasting beans. The heavy, iron ring on a church door, a handle that feels ancient and judgmental, demanding a certain posture, a certain state of mind, before you even dare to pull it. For a long time, I believed that all doors would ultimately lead to a variation on one of those themes: indifference, hostility, or outright terror. The world felt like a series of rooms I was not truly welcome in, each guarded by a knob that was either a puzzle, a threat, or an insult. My own front door was the only place that felt neutral, and its knob was simply a tool for my own isolation. A lock against the world. And then, one day, I encounter a new door. A new knob in a home. This feels different. I’m hesitant. My hand, conditioned by memory, approaches it with the caution of a bomb disposal expert. My fingers brace for the cold, the cheap, the wobbly, the hostile. But this one is different. It’s a simple lever handle, but it’s not the cold, corporate steel of a public building. This one is made of dark, smooth wood, worn gentle by countless hands. The wood has absorbed the warmth of the house, of the people inside it, and it feels alive to the touch. It’s not hot, not cold. It’s just… a neutral, gentle presence. Like skin. My fingers close around it, and the wood is smooth, solid. There’s a slight indentation where a thumb would naturally rest, a small, unintentional accommodation polished into existence over years of use. It tells me this is a place of habit, of comfort, of return. This is a handle that has been grasped by the same hands, day after day, in loving greeting and in farewell. I press down. There is no squeak of protest, no cheap rattle of a loose mechanism. There is only a deep, solid, well-oiled _click_. It is the sound of something working exactly as it should. It’s a sound of reliability. Of trust. It’s a sound that says, "Everything is okay. Everything is secure." It’s the opposite of the jiggle. It is its antidote. This doorknob, this simple piece of wood and metal, tells the best story I have ever felt. It speaks of a space where things are cared for. Where a small detail, like the sound a door makes, matters. It speaks of a person, or people, who have built a life here, who have polished the surfaces with their very presence. It speaks of intention, of quiet love invested in the bones of a home. It does not feel like a barrier to keep me out or a trap to keep me in. It feels like a welcome. The first handshake is warm, steady, and unafraid. And as the door swings open, releasing a breath of air that smells like old books and brewing tea and something I can only identify as peace, I find that my own hand has gone from a tense claw to a relaxed palm. The elephants in my ribs are quiet. The ice in my lungs has melted. I am home. So yes, show me your doorknobs. Tell me, without saying a word, what I am about to find on the other side of the door. Tell me if you’ve thought about the hands that will follow yours. Tell me if your space is a fortress, a facade, or a sanctuary. Tell me the story of your world, one handful at a time. I’m listening.

When I ask about his toughest day at Meta, I'm half expecting something like the suicide of 14-year-old Molly Russell, who had been viewing self-harm images on Instagram (the coroner ruled she died
"while suffering from depression and the negative effects of online content"). But, instead, he picks the "very, very uncomfortable" decision he took to suspend Trump from Facebook in 2021 for incendiary posts during the Capitol Hill riots. "I found that really weighed on me very heavily and still does because, on the one hand, I felt very clearly that the content rules of the company had been violated and, on the other hand ... it's an unelected private company making a decision that affects the public realm. And he was the outgoing president of the world's most powerful democracy."
He would still defend the decision, but the precedent set troubles him. "In the end, in a democracy you want democratically accountable figures to thrash it out."

Further evidence that a predominant system of political communication is no longer appropriately run as a private company, but rather should be run as a utility — so there is indeed democratic legitimacy to such necessary decisions.
