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
Non-German but I am in the EU. Didn’t find it odd at all. Just assumed it was “flow market” in German.
Close. It’s flea market.
