I just tried this with my gf. She was seating across to me and When she received the text message, she was confused and told me "OMG how do they know my name?". Then I explained to her what it was, she obviously told me she wouldn't have answered it. Maybe it'd be cool to find a way to validate the sender to the receiver without losing the anonymosity. Really digging this though! I always hate having to ask people their sizes, what they like, etc...
