How about an opt-in toggle to display the year each account was created?

I'm right on the boundary of the slopocene, not sure if in or out.
Or grade accounts by the logarithm of how many accounts were registered before them, like Slashdot. (This is tongue in cheek as I assume yours was.)
So now we're going to create a black market for old HN accounts?
Am I too late to get ahead of the curve and stockpile some, while they're still relatively cheap?
