Locacha is a chat room full of people near you. You tell it your location, and it lets you chat with the 30 Locacha users who are located closest to you. You can run it on your iPhone or at Locacha.com.

The service launched last week and the creator just put it on Reddit. It's tiny right now, so the 30 closest people to anyone are still scattered around the world. But I bet this thing is gonna blow up this week, becoming the new Chatroulette, and you'll be able to chat with people from your own neighborhood.

Come be a part of that early dawn before it all goes crazy.
