ADWEEK - Neighborhood social network Nextdoor teamed up with Verizon on The Big Neighborhood MeetUp, a monthlong call to action in honor of Neighbor Month in September and part of Verizon's #ACallForKindness campaign, aimed at encouraging people to recognize and build vital relationships with those nearby and to showcase the power of kindness. The two companies will host #BigNeighborhoodMeetUp events in four cities such as Chicago; Houston; Oakland, Calif.; and Raleigh, N.C. A fifth #BigNeighborhoodMeetUp event will be held in New York in October to coincide with Advertising Week NYC.
