Recently, the Internet has a new service - a social network Fat Door.com. With proper development, it should become very useful and popular: it’s about the average between Google Earth and the Yellow Pages.
Imagine your area in digitized form - all neighbors with their contact details. In the future - and organizations. You do not need to look for contacts, remember who your name is, everything on the interactive map is in full view. Of course, if the new service is advertised normally, then it will take its niche.

Another thing is that some users may not like the idea of specifying their data so that the neighbors can contact them if they wish. Good intentions can break about the suspicion of people reasonably hiding their personal data and email addresses. Therefore, FatDoor.com, with all its charms, is unlikely to take root here.
