Project ideas from Hacker News discussions.

I wish people were more public

📝 Discussion Summary (Click to expand)

Here are the 3 most prevalent themes from the Hacker News discussion, supported by direct quotations:

1. The Dangers of Surveillance and Weaponized Data

Many participants expressed deep concern that public sharing is now too risky due to pervasive surveillance by corporations and governments, as well as the permanence of online data. This permanence means that innocent or uncontroversial content can be "dug up" years later and weaponized, making privacy a necessity for self-protection.

"There's no way I'd be comfortable going back to the way things used to be unless the web becomes better -- and I don't think that's happening anytime soon." — JohnFen

"Everything online is preserved, so it's easier and safer to just not to participate at all." — 000ooo000

"I read in private, build in private, learn in private. And the problem with that is self-doubt and arbitrariness." — zephen

2. The Prevalence of Harassment and Unpredictable Social Risks

The discussion highlights a fear of public discourse due to the high likelihood of encountering bad-faith actors, harassment, and "cancel culture." Users argued that the internet's scale guarantees exposure to individuals who will attack for reasons often unrelated to the content itself, and that "real name" policies do not mitigate this threat.

"If you want others to broadcast their lives, I don't think that moralizing is enough; you gotta offset the negatives. Which basically means 'positively engage', but we mostly don't do it on forums such as Twitter." — nospice

"Even if they speak your native tongue, they'll have to learn how to interpret your slang and texting shorthand... My suspicion is that history is going to remain remarkably unchanged... For some historical figures we'll have mountains of material. Others, despite their importance, will be complete enigmas." — beloch

"If you're on the internet long enough, I think you learn that openness has plenty of downsides. You indirectly interact with tens of thousands of people and in that set, there will be people who don't wish you well..." — nospice

3. The Value of Pseudonymity and Niche Connection

A significant counter-narrative emerged valuing the internet as a space for connection, but specifically through pseudonymity or specific handles rather than real-world identity. Users emphasized that this allows for genuine, risk-managed sharing and helps filter for "like-minded" individuals (the "honeypot for nerds" effect) without exposing one's offline life to scrutiny.

"claxxon knows about cisco networking and zerg knows about the best punk bands in the chicago area. Their real names? Not needed, wanted, or relevant, and we're offended you even asked, noob!" — phendrenad2

"I treat any of my public facing information as a honeypot for nerds (i.e like-minded people). In real life, if I meet interesting people, I point them to my website. If they reach out with questions, I know I found 'one of my people'." — RatchetWerks

"Pseudonymity allows people to freely express ideas with others without fear of it seeping into all aspects of their lives. How else would individuals share and get feedback on things like health issues, relationships, employment, etc. without the threat of repercussion?" — derangedHorse


🚀 Project Ideas

Private Persona Sentinel

Summary

  • A browser extension and background service that automatically classifies and compartmentalizes a user's online writing based on risk, so they can share openly without exposing themselves to future context collapse.
  • Core value proposition: Enables "working in public" by ensuring different parts of your identity (professional, hobbyist, political) are siloed and can be selectively retired without deleting content.

Details

Key Value
Target Audience Developers, writers, and academics who want to share ideas publicly but fear future repercussions from context collapse or surveillance.
Core Feature Analyzes user-generated text in real-time (using local LLMs) to tag content by persona/risk level (e.g., "work-coding," "political-rant," "personal-journal") and wraps it in a persistent, encrypted identifier.
Tech Stack Browser Extension (JS/TypeScript), Local LLM (e.g., llama.cpp), E2E encryption, IndexedDB for local storage, WebRTC for P2P backup.
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters like 000ooo000 worry about "dredging up common things said in 2010" being controversial later. This tool allows them to tag old opinions as "past self" and sever them from their current professional identity.
  • Addresses the "permanent internet" fear expressed by vjvjvjvjghv ("people will give you a hard time for something you wrote 10 years ago") by allowing users to cryptographically burn keys to specific personas, making them anonymous or unlinkable while keeping the content up for historians.
  • Potential for discussion: It bridges the gap between arjie's desire to be an open archive for humanity and iamnothere's desire to avoid weaponized context collapse.

Legacy.link (The Anti-Prescription)

Summary

  • A platform designed to curate a user's digital legacy for historians without exposing them to living predators, solving the "privacy vs. preservation" paradox.
  • Core value proposition: Ensures your "tomographic cuts of the mind" (beloch) are preserved for the future but locked behind time-based or event-based cryptographic locks, safe from today's bad actors.

Details

Key Value
Target Audience Privacy-conscious users who want to leave a legacy for future historians (or family) without risking current-day harassment (nospice, hellouruguay).
Core Feature "Dead Man's Switch" for data. Users upload journals, code commits, and emails. The data is encrypted and stored decentralized (e.g., Arweave/IPFS). It can only be decrypted by a designated "curator" (e.g., a library or future family member) after a set date (e.g., 50 years post-death) or upon verified death.
Tech Stack Cryptography (Shamir's Secret Sharing), Smart Contracts (Ethereum L2/Arbitrum), Decentralized Storage (Arweave/IPFS), Biometric verification (FIDO2).
Difficulty High
Monetization Revenue-ready: One-time "entombment" fee or annual maintenance fee for the key management service.

Notes

  • Directly addresses beloch's historian perspective: "Every tweet, blog post... is a tomographic cut of the mind." It ensures these cuts aren't lost to "chaotic server turnover" but also protects Anonyneko from government persecution while they are alive.
  • Solves the issue mentioned by hellouruguay regarding fear of being "cancelled" for past statements. By decoupling publication from visibility, users can contribute to the historical record immediately while limiting social risk.
  • Practical utility: Could serve as a high-trust time capsule for sensitive family history or controversial technical debates that shouldn't see the light of day until emotions cool down (decades later).

ContextGate: The Semantic Pseudonymity Layer

Summary

  • A middleware for forums and social platforms that allows users to split their identity based on context, preventing "context collapse" where acquaintances, employers, and strangers see the same content.
  • Core value proposition: Restores the "vibrant communities full of people with names like 'claxxon'" (phendrenad2) but with modern tools to prevent de-anonymization and harassment.

Details

Key Value
Target Audience Users of technical forums, open-source contributors, and marginalized groups (01HNNWZ0MV43FF) who need to participate in niche communities without linking those activities to their professional or real-life identity.
Core Feature Client-side encryption and reputation siloing. Users post using a "Context Key" (e.g., "Python-Dev-Key" vs. "Politics-Key"). Replies are segregated; a user cannot see your "Politics" posts unless they also possess that specific key, even if they know your real name.
Tech Stack WebAuthn, Client-side encryption (WebCrypto API), ActivityPub extensions, OAuth2 for context-specific login.
Difficulty Medium
Monetization Hobby (Open Source), potentially "Revenue-ready" via Enterprise SSO integration for internal corporate forums.

Notes

  • Fixes the "context collapse" fear mentioned by jay_kyburz and cgriswald. You can be "Mr. Rogers" at work and a "filthy pinko commie" in your niche hobby group without the two leaking into each other.
  • Allows SXX to participate in discussions without fear that "AI news slop" will conflate their technical contributions with their political views to create a "supervillain" narrative.
  • Practical utility: Reduces the barrier to entry for petterroea who hesitates to share technical dissent ("complaining about Cloudflare") for fear of professional blowback, enabling safer, more honest discourse.
