Still working on this project so I can't show anything, but basically I'm building Letterboxd for cafes, i.e. a review site with social elements for coffee enthusiasts. You can log visits to cafes, review them, rate them, follow other people to see where they've been going and what they think about those places, and so on.

I don't know much about coffee myself, so I'd like to ask coffee enthusiasts: what would you be looking for in a site like this? What info do you want to know about cafes that isn't available in Google Maps? What features do you think would be cool?

And where would I be able to post this site (other than Product Hunt/Indie Hackers/etc) once publishable (and/or what are some good places to ask for feedback)? I checked r/Coffee but they don't allow any self-promotion or apps/sites even if they're free.
