The city I live in made some sort of deal with Nextdoor.com and it was presented as something we should try out. I don't remember the details, but each neighborhood had to get some number of signups or it would go away. I signed up, and was thoroughly unimpressed. After searching for a way to un-signup, I resorted to emailing the site. They said if I leave, I cannot sign up again. What kind of lame threat is that? I'm glad I left and haven't looked back. No idea if it ever caught traction here.
