There is a website out there called Nextdoor in some communities. It’s like a community bulletin board. In the one I’m in, there are posts about lost or found pets, posts seeking recommendations for snow shoveling, child care, plumbing, maid service, handymen, posts offering the same stuff, posts advertising and seeking used baby stuff, posts about suspicious people in the neighborhood, posts from the local police station about crime in the neighborhood, people bitching about neighborhood activities like not picking up after dogs and not shoveling, posts bitching about racism in the previous post, and requests to borrow things like a staple gun. (The requester offered to leave her chihuahua as collateral while she borrowed it.)
My address etc. is visible only to the people in my neighborhood, but I can see posts from all adjacent neighborhoods. It’s kind of neat in a way–like if there is an unexplained really loud noise, someone will get on there and either explain it or question it. It’s also another way to waste time on the internet, like I needed that.
This seems to be a national thing but I have no idea if it’s available everywhere, because when I google “nextdoor.com” I get the one I’m already signed up at.
