Show HN: Herenow – Send and receive messages within 100 metres of you

It was fun to hear about a strangers toilet experience when I landed at Auckland airport - it's like leaving tech graffiti in interesting places :)

I'm a friend of Bens and I've been playing around with the android app. Quite a few messages have been left around wellington. It's fun.

Nefarious usage will ensure this app has a place on my phone.
