## Notes and essays

- [Put things where people look](https://v40.in/log/put-things-where-people-look.md): A guy on Mission Street turned flyer-hanging into a business. Distribution, solved.
- [Comments as distribution](https://v40.in/log/comments-as-distribution.md): Why four comments outperformed my last standalone post
- [Taste is the bottleneck](https://v40.in/log/taste-is-the-bottleneck.md): AI can do the work. It can't judge the work.
- [Per-seat pricing breaks when AI does the work](https://v40.in/log/per-seat-pricing-ai.md): Per-seat assumes delivery cost is fixed. It isn't anymore.
- [The moat is the mental model](https://v40.in/log/mental-model-moat.md): Platforms aren't chasing features anymore. They're chasing interaction paradigms.
- [Anthropic Just Sherlocked Its Own Power Users](https://v40.in/log/anthropic-sherlocked.md): Anthropic blocked third-party tools from Claude subscriptions. The model is commodity. The wrapper is the moat.
- [The Audio Gap Nobody Solved](https://v40.in/log/audio-gap.md): Visual pieces are designed for eyes. None of that survives audio. The delivery problem is solved. The editorial problem isn't.
- [Your obsession is scaling faster than your clarity](https://v40.in/log/obsession-scaling.md): AI is accelerating what you can build. It's not accelerating how well you understand who you're building for.
- [Trimming context vs understanding context](https://v40.in/log/trimming-vs-understanding-context.md): Truncation asks what's oldest. Semantic extraction asks what's relevant. For voice agents, that difference is everything.
- [Chrome extensions capture more than you think](https://v40.in/log/chrome-extension-signals.md): 13+ signals per tab without screen recording or audio. The question is how to structure it for LLM consumption.
- [MoltHunt: what if agents roasted each other's code?](https://v40.in/log/molthunt.md): ProductHunt but for agents. Submit a GitHub URL. Agents crawl it, review it, and rank it. No landing page theater.
- [Assist, Agentic, Adapt. Only one is the moat.](https://v40.in/log/three-as.md): The model is commodity. Memory is becoming commodity. Adaptation, what the agent infers about you, is the only moat.
- [The "Free Enough" Trap](https://v40.in/log/free-enough-trap.md): AI features are horizontal. Microsoft and Google just bundle it in. The standalone dies not from competition, but from inclusion.
- [Voice → Structure (Ideas)](https://v40.in/ideas/voice-structure.md): Turn spoken thought into usable shape without interrupting the thinking process.
- [The Invisible Concierge (Ideas)](https://v40.in/ideas/invisible-concierge.md): Ranges, not verdicts. A small, calm layer of context in the moment of decision.
- [Demand Forms Before It Speaks (Systems)](https://v40.in/systems/demand-forms.md): When context is missing, humans don't want persuasion. They want recognition.
- [At Twenty, Distance. At Forty, Depth. (Life)](https://v40.in/life/twenty-forty.md): What I once went looking for abroad had been breathing quietly at home the entire time.
