RadiopaperCommunity service — comments reveal after recipient accepts
Tries to fix public-thread abuse by withholding replies until the counterparty accepts. The stronger signal is the stack: email-first UX and a $40/month burn make this pattern cheap to test.
- Core mechanic: a reply stays private until the other party replies or accepts it, filtering drive-by trolling before it becomes public.
- Users can participate entirely through email; replying to a notification publishes back to the site, which lowers login friction for discussion products.
- Infra is deliberately lean:
Vue+TypeScript,Go,Cloud Run,Firestore,Firebase Auth, plusGmail APIandSendGrid. - The team says a few hundred active users still fit under free-tier limits, with overall burn around $40/month from tools like
Sentry,Mixpanel,GitHub, andSendGrid.
