Nextdoor.com is unique among social networks. There are (almost) no memes or cat videos, very little political content (though some; see item #10 below), and no one showing off their recent exotic vacation photos.
Instead, it’s geographically based; the content you see (and the users you see it from) are based on what neighborhood you live in. Nextdoor covers 260,000 neighborhoods in the U.S. and another 80,000 in 10 other countries.
It’s not often included on lists of the largest social networks. But if it were, with 95 million users, the platform would rank as about the 30th-largest globally (bigger than Rumble, smaller than Medium) and roughly the 20th-largest in the U.S..
