I've built an ersatz FourSquare clone for the Fediverse!
For now it is single user instance (me) and runs on a simple server with no database - just a couple of PHP files.
It geolocates my phone's web browser, shows nearby Points of Interest using OpenStreetMap, lets me attach a short message & an image with alt text.
Then it posts it to its Fediverse followers. The post contains geotags which *some* ActivityPub clients can see.
