Description
The idea is simple: click any place on the map, propose a name, others vote, or it will be auto-accepted in ~5min. No account needed for fresh locations or name duel - only to challenge already-renamed places or vote to prevent abuse. 40k renames so far, and surprisingly people mostly behave. Some names are genuinely creative and I keep learning random geography facts just by watching the map (did you know someone mapped every single animal in a Taiwan Kaohsiung zoo on OpenStreetMap?)Non-commercial, just a side project. Stack is SvelteKit, MapLibre, 40GB vector map self-hosted on Cloudflare R2.Please don't use this for navigation.
