people have largely been 'personality terraformed' by the big tech algorithms. it's reaaally hard to "undo" that. it's as much witchcraft/blackmagic as it is a sweeping behavioral change in culture and secondarily 'online society.'
imho, a new site would have to be built, and it would probably only be inhabited by old people who remember the 'before times.'
which, imho is probably why this site is fun, people are polite, they're willing to interact thoughtfully, and share opinions and information with one another.
my favorite internet network has always been IRC. therein because no matter what else seems to happen, there are always people that not only remember it, but use it on a regular basis, and don't need to be taught how to use it. simple, intuitive, and logical.
