Not the prettiest page on the web, but I can now Geolocate my phone and find the 25 nearest named places on #OSM.
Next stage is making a button to send that location to my ActivityPub server to send out a message.

I've just reposted a public status from my new location check-in service.
It doesn't handle replies or likes, but you can follow it.
Expect buggy and untested weirdness 🙂
