Over the past year or so I’ve been playing with the idea of a decentralised social platform based on your location. By putting physical location at the centre of the experience, such a platform could be used to bring communities together and provide a source of local information when travelling. Please let me know what you guys think.
Oh indeed, there are ways and means of doing it, it just doesn’t tend to get done that way because examples like mine are figuratively and literally, edge cases.
It can’t really address the other point, in that you may have to allow for population density.
