Nextdoor is “a private social network for you, your neighbors and your community.” Think Facebook, but just for your neighborhood and some of the areas close by.
The free site seems to be a good way for neighbors within a few blocks of each other to communicate directly, like some of the area Facebook or Google groups, but with the added caveat that users have to confirm their address to participate and everyone has to use their real name. It seems like it would be a particularly good platform for the civic associations to use to share information.
The site offers the service to area neighborhoods, including Church Hill, Church Hill North, Union Hill Chimborazo, Fairmount, Mosby, Brauers, and Fulton.
