Show HN: Matching people based on their saved places, not their profiles

I exported my Google Maps saved lists, compared them with a friend's, and realized our overlapping places said more about compatibility than any bio. So I built Common Ground — paste two list URLs, swipe through your places, and see what you share. No signups, runs in your browser. Vibe-coded in an hour
