We believe that in days of new computerized and distant ways of communications, emotional connection between people deserves a special treatment. We believe that happiness really matters. With all the gratitude for internet itself, making endless people closer to each other online, we feel, how at the same time internet is enlarging the distance between those, who appears to be nearby in fact. In this case we suggest our geolocation chat as a tool to get in touch with those who matters the most - people surrounding you. Imagine air filled with thoughts, attributed with a mood? - Here we go! - absolutely anonymous. Share your mood with the world! - Get a feedback or support someone in time of need! - share your thoughts and get to know the most relevant information around or on the other side of the planet. It is so much fun! - Take time and discover! We truly believe the mood of a man plays an essential role in his life. As the collective mood of people plays a crucial role in the whole world, we are inspired by the idea to graphically present it in real-time on the map, similar to weather - so we create the geolocation mood index and its history. When the whole world is talking of building of a sustainable future, really how can we build anything sustainable for human beings, if we can't measure how our decisions effect our lives — live of the society? Hell of a rhetorical question. Real-time dynamic heat maps of mood emissions, waiting for you, filled with users' messages and emotions. Think and analyze it! - Geolocation mood index is a very significant and aggregated indicator for any type of correlation from politics to weather.
