I'm no fan of FB, but the problem is deeper than FB. If FB vanishes overnight, some other service will take its place, and the same people who posted on FB will post on whatever the new website/service is.
Yes, it would be nice if FB fades into obscurity. But what would be nicer is if people had some basic decency and responsibility (everyone, me included) before posting clickbaity, flammable, junk stuff. I have no clue how to achieve this, but the internet used to be a fun place (for learning, niche topics/ideas etc) - those days are gone, and it sucks
Nextdoor is a platform meant to connect communities and services.
It's as bad as Facebook - and even sadder in that you know the folks are truly local, and still just as awful.
Are our only options truly old-school, disconnected approaches versus wading through trolls in a hyper-connected world?
Surely there's something else, and maybe it has nothing to do with tech as we know it.
