It's not hard to do, probably take me 10 minutes. Just not sure if we want to. I don't think there is a strong case for/against it. I would make the case against it as such:
-1. This is a prelude number, thus it is called 0. Wait, let me make it -1 to prelude the prelude
0. Caveat: Frank convinced me that anything older than 48 hours is worthless. So 48 is the same as 448
1. I prefer the cleanest look possible
2. If there is 1 review, it means the latest is older than 48 hours.
So instead of a date it's more of a binary flag. 1 review means old. More than 1 means it has been updated.
