How do I tell someone on the bus to check out this website?

This looks cool! Any android apps?

Ad-software huh ? Maybe this could solve the monetisation issue of let's say PeerTube

What localities does this operate in so far?

Cool. If u can host it as a tor hidden service that is a large an influential market that might benefit from such a thing. Haven't looked but it might need some additional features to work as a decent platform in that sense.
