It can be both. It seems obvious that a thing like Twitter ought to exist. The social system details, I'd agree, are full of unforced errors that lead to terrible outcomes. But the centralization is a real problem too. We can try to fix both.

The essential element of twitter is asymmetric following + broadcast at global scale and penetration. Beyond that, I think the social system details are wide open.
