I am the president of City Chattr, a neighbourhood social network in Ontario Canada. This is a grassroots attempt to connect local residents to their neighbours and to the local business that serve the community. For Visitors they are able to talk to the local residents to make it easier to discover the area. for Residents they are able feel more connected to their community and get referred to local professionals. For Business the social proof that comes from a neighbour referring your services provides a great ROI for time and money spent on promoting your company on City Chattr.
