Assuming it's a one mile radius for everyone, making it a chat room the app would either need to intersect or union everyone's area... This would make the novelty of the app unusable or pointless, respectively.
Yeah, I wonder how that works actually. If radius A intersects with B and C but B and C don't intersect with each other, do B and C see A chatting to someone who they don't see?
That's how mobile radios have always worked... CB, FRS, GMRS, etc. Definitely not a new problem. Repeaters can mitigate the problem somewhat.
That's a really great question, my curiosity is also piqued.
would really like to know more about this as well.
A previous app (now defunct) named ChatSquare would group people together based on the nearest Foursquare location.
Looks like there are "areas" to unlock.
Yeah that was the question I initially had - I'm assuming it's a chat room, which I like a lot better.
