Facebook testing Neighborhood app in San Diego Abbie Alford, Reporter Facebook could be giving Nextdoor some competition. During the pandemic, many neighbors turned to their community and online resources. Now Facebook is testing Neighborhoods, an app where you can connect with neighbors. “We are trying to build tools throughout the entire experience to build these really strong and vibrant communities,” said Reid Patton, Product Manager, Facebook Neighborhoods. Facebook says Neighborhoods is being tested in four U.S. cities including San Diego, Baton Rouge, Charlotte and Newark. “We saw people in San Diego were using Facebook to connect and participate in their local community,” said Patton. "Facebook Neighborhoods takes all of the local community experiences you care about on Facebook and brings them into one centralized destination."
