As this project appears to be fairly unknown in the fediverse still, I’d like to use this opportunity to advertise Flohmarkt. This Fediverse equivalent of Facebook Marketplace already has some instances up and running - see here: https://codeberg.org/flohmarkt/flohmarkt/wiki/flohmarkt-instances
Will keep an eye on this, but there is nothing too local here (No, I can’t host something myself). Given how the specification says there should be a location and radius per instance, some admins are really slacking on putting that info in the description.
