I have a background in marketing, web analytics, and technology and so on. My community recently moved to Nextdoor. It is perfect for nosy, stuck up, social media craving, power hungry busy bodies. There are constant SPAM like postings from other adjoining communities. Poor organization for community documents. Perfect medium for people who don't have any sense of how to use social media. The leads are the worst. When they made the switch the board said, "It manages itself!" And, "It's FREE!" Read the fine print nothing is free! Nextdoor is collecting a copious amount of information from member's browsers. Your demographics, shopping history, websites visited,… They are building a marketing machine.

My community's site just had its first libelous post and I am sure there will be more to come…Yeah!
