For what would you use knowing real-time density around you?
I am playing with the idea of an app displaying real-time density of people to map out where and how many people are in a location (anonymously).<p>Would there be a situation where you think this could be useful?<p>As a recent encounter (travelling for holiday), I figured that it would be nice to see where people really are, mainly because I got hugely disappointed by biased Foursquare and Tripadvisor recommendations.<p>Any suggestion&#x2F;experience for when knowing real-time where the crowd is could be useful?
