Nextdoor posting can be quite entertaining. Think back to the infancy of MB's where most people didn't get how they work, how to answer a post, no idea what sarcasm is, or the invariable "I have X qualification, therefore I win" posts -- that is nextdoor. Admittedly I've started more than a few information skirmishes, primarily to light the brush and see what kind of responses I get. I have been surprised that in my area there have been more conservative, red-pilled responses and posts than I had previously thought would be; but at the same time the useful idiot posts are in grand numbers as well, which is sad.

With all that being said, as long as you don't try to convert/redpill with one post(b/c that isn't going to happen), ND would be a great place to slowly try to wake people up. The bastard lefties coordinate like that, hell we see it on the GA all the time, what's stopping us from getting the message out?
