Tell HN: You know what's the best? When a stranger tells you about your product.

So I was at Starbucks earlier a few hours ago, drinking coffee with a friend and some of his coworkers when we began talking about iPhone apps (one of them recently bought a new iPhone and asked what apps were recommended). So we talked about most common ones like Instagram, flashlight, temple run, paper, etc when one of the other guys mentioned that he recently signed up for an app that was coming soon he thought was pretty cool. He started to describe it and I almost choked and snorted on my coffee- he was talking about our app! It was an amazing moment, knowing that someone out there that you don't know is talking about your product. Any similar experiences out there?
