How many folks have actually _tried_ this app yet? I downloaded it, and despite having been a user of Path, Instagram and just about every other photo sharing / social media app that's popular, I've yet to get any interesting result from it. Maybe I'm doing it wrong, but how the hell do you use this thing? Am I supposed to just randomly take photos and hope other people nearby are using the app? Why do I care if they are?
