Every good idea is a solution to a problem. In the case of San Francisco based start-up Nextdoor the problem is that neighbors no longer get to know each other and truly communicate. The small-scale social network is trying to solve this by introducing a digital medium for neighbors to exchange messages, ask for help or organize local events. Every neighborhood, suburbia or small town has its own page, and all visible content is generated by people who actually live there. This is ensured by a secure registration and verification procedure based on the user’s physical address. Once people register in their neighborhood, they can send messages, write posts or questions, but they also have access to all previously shared information, meaning that answers can be found even without asking.
