That'd be great to have one since I see the potential of coffee niche. Some people I talk to IRL even some relatives either wants a) becoming/ already a barista, b) having a coffee shop c) suddenly a coffee snob. It would be cool to have a front-end for sure with its working token, good curation, and moderation system. And yes, advertising within the system and pay to @null account may work. I don't know but has NM does it? It would be nice that there are natural shops or stuff that are exist there and advertise their stuff, don't you think?
