NextDoor is really useful if you live in a high crime area. I live in a neighborhood that had the misfortune of having a public housing apartment complex built in the middle of it which has resulted in a tremendous amount of crime. As a result almost everyone in our area is on Nextdoor so you know about who has been robbed/attacked/burgled most recently.
