If you build something as an individual developer and want the world to use it, the fastest path is to show it where the world's developers gather: dev.to, Product Hunt, Reddit, and Hacker News (HN).
Once you've translated your product into English (i18n), you can reach people everywhere through these places. But you can't just post and hope. Each one has its own etiquette — and HN in particular is unusually hard.
Why HN is hard
- It's an English-speaking technical community where promotional-sounding posts sink fast, or get flagged.
- It has its own conventions: how to title a story, when to use Show HN / Ask HN, karma, ▲ upvotes, and the norms of comment discussion.
- A single misstep stays on the record. There's no safe place to practice.
So I built a practice ground
Hacker Noroshi is a place to practice the look and the mechanics of HN safely, in Japanese. You can try the same etiquette as the real thing — submitting, ▲ voting, commenting, hide, favorite, flag — in an environment where nothing is lost if you slip. Turn on Assist mode and it bridges the English terms (karma, Show HN…) into Japanese as you learn them.
Get comfortable with the conventions here first, then step out to the real HN, dev.to, Product Hunt, and Reddit. That's what Hacker Noroshi is for.
