Kuro5hin, Slashdot, heck- The WELL all still exist. Old-school platforms and communities are on the internet. So do old-fashioned personal websites. They might have a pittance of users, but they're out there. Is that not what you want? But what you can't want, is for a large amount of people to use them, if they have no inclination to.

It'd be great if everyone started making their own Neocities site. Or even just drop contemporary social media and join the new Friendster (https://news.ycombinator.com/item?id=38021802) or Spacehey. But the cultural impetus just isn't there.
