I’m working on a location-based feed. Posts are attached to user location.

If I arrive in a new place, I’d be able to get a “feel” for the place by browsing top posts for current location.

Also useful for annotating the environment. Eg. “Coffee van here on Sundays”, or “aggressive dog seen here”.

I don’t think there’s much demand for such a thing, but I like the idea of having a feed relevant only to my current location.
