Nextdoor is one of the best things on the internet. Easily the most constructive large scale BBS type things I've seen since early craigslist. If yours is nuts: it's because the people around you suck. I'm as misanthropic as they come, but the people around me are fucking great.
I'll admit it was awful when I lived in Berkeley, but so were the people around me.
"It's because the people around you suck." Isn't that the core problem with all social media? If people didn't suck we wouldn't be having this discussion about facebook.
FB is terrible as it puts your aunt Mabel, your 3rd collitch GF, some guy you bought weed off of in HS, and some dude you met at an industry mixer together with 100 of your closest pals and lets them fling poop at each other. You can quit; I did. Don't miss it!
Nextdoor is great; lets me know what the neighbors are doing and helps me pick out great local services. Some dudes above pointed out you need some common interest for it to work: being a good neighbor counts as a common interest!
