Thanks, glad you found it fun! That was the main goal for this initial version.

Good question on evolution. Some ideas that come to mind, building on the core location concept:

Ephemerality: Maybe messages could disappear after a set time (e.g., 24h via TTL indexes) to keep conversations fresh and less like permanent archives.

Discovery/Activity: A heatmap layer (using something like Leaflet.heat) showing areas with recent message activity could be interesting for finding active spots without needing to click every pin. Could aggregate message counts per pin/area on the backend.

Mobile: A native app could enable things like background notifications for nearby activity, but that's obviously a much bigger step.

Definitely open to other thoughts if people find the core idea engaging.
