An 18-hour half-life for PH + HN + GitHub
Product Hunt, Hacker News, and GitHub don’t share a score. LaunchSignal is a public radar that mixes them with one bet: heat × exp(−hours/18). Live list (and JSON): https://launchsignal.ai/?utm_source=indiehackers&utm_medium=post&utm_campaign=waitlist — not an idea-validation tool (that’s launchsignal.io).
GitHub long search queries return 422, so we keep those queries short.
What half-life would you pick instead of 18 hours?
