Say what you will about public forums (Bluesky, Twitter) but if you post complete nonsense you are typically going to get roasted. On Nextdoor you can say completely wrong stuff and it shows up just the same as everyone else which is pretty toxic IMO.
I feel like a lot of my time on NextDoor is just explaining to neighbors the very, very basic stuff that local government does. I keep forgetting that despite living in the information age even retirees know hardly anything about local government with the decline of in-depth local news.
