"Already seen too many cats on there for one day though. One is too many."
Well, that's the fatal flaw of this recurring "let's build a local social network!" idea... if you wanted to indiscriminately talk to people all around you in your area, you already would be. By and large, you don't have every neighbor on your Facebook because you don't really want them there.... I still haven't seen a compelling use case that isn't based largely on wishful thinking or nostalgia (often for eras not lived in by the nostalgia-ee that may or may not even have existed...), rather than being based on some sort of witnessed need.
Once they gain traction, you will get too many infections from around the world and may be interesting in what is happening local.
I like how vague it is - it is allowing the the users to define it's purpose. A bit like Facebook.
