ALL THINGSD - Feb 12 - Nextdoor is a private social network that focuses specifically on the neighborhood. Users communicate with one another to form tighter bonds around their community, only sharing identity information directly with those inside their area. The company launched an update version Nextdoor 2.0. Instead of restricting users to their previously cordoned off districts, they’re able to post information to nearby neighborhoods, those bordering the area a user resides in. Greylock Partners led a new funding round of $21.6M, adding managing partner David Sze to the Nextdoor board. With upwards of $40M raised, the company has plenty of room to grow.
