Networking Neighborhoods: One of the hottest categories in geolocation is neighborhood networking. The vision for many of these apps is to strengthen the very fabric of our communities. With DeHood, you can keep track of what’s happening in your neighborhood, share your favorite places, and grease the wheels for actually meeting people. After all, if you’ve made contact through the app, it’s a lot easier to say “Hello” in the real world. Blasterous is another that lets you share information locally, whereas BlockChalk does this on an anonymous basis. Finally, NeighborGoods uses your street address to facilitate one-to-one borrowing and trading of useful stuff. In the end, making connections with your neighbors can lead to safer, more productive, and more sustainable communities.
