Ah, I see. The distinction is between superlinear rewards based on stake and superlinear rewards based on individuality. Superlinear rewards distributed based on individuality is a fundamentally different thing. As was explained in the post, with superlinear rewards distributed based on individuality, a self-vote gets you nothing more than a vote for someone else because your stake is irrelevant. All that matters in such a case is whether the thing you vote on receives more upvotes in the future from many more individuals regardless of their stake.
