It's an outdated concept, we all know people don't surf the web anymore. And the larger it will get, the less likely people will. Have you tried using RSS, just measly collecting your favorite sites with the off chance that they support it? It's a mess and no surprise it died as everyone flocked to Facebook, Twitter, etc.
People need some sort of platform and that's why ActivityPub / Fediverse is a lot more promising. Social networks aren't the problem, just the one's we've been using.
