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
How do I tell someone on the bus to check out this website?
“Just go to fedi.markets”
I don’t see an issue. With any service on the Internet you direct people to the URL of an instance not the underlying code. If they saw “powered by flohmarkt” and asked what that was, I’d say it was German for “flea market” and I imagine they would be satisfied with that.
