It wouldn't be just friends, but that's how I phrased it there. I called it "supporters" in these 280 characters:

"Some people just get along. They are compatible. They mesh.

I think it's possible to predict whether any two people will hit it off, and to create groups composed entirely of highly compatible, highly synergistic people.

What will happen when EVERYONE has a THOUSAND SUPPORTERS?"

And it wouldn't just be friends or supporters, either:

"Just as the system can find those who are your mirror reflection by minimizing adjacency distances, so it can find your very antithesis by maximizing them, as well as anything in-between."

That's from this post which explores implementation: https://zeroprecedent.substack.com/p/a-technique-for-generat...

I think after implementation, adoption is inevitable since the value is truly insane, better than anything else online (unless you're antisocial, etc.)
