Oh. The metric I suggested was of median interest. Meaning, look at what others found interesting. The question becomes, was it only of median interest to everyone or was it of median interest because not everyone observed it.
Personally, I observe a significant difference in votes simply by the time of day I post something. Which IMOHO means some people only look at current posts when they happen to appear online and don't look back for the rest of the day. Or they are making assumptions that they won't look because it's not already up voted. That type thing.
Seems like an impression count on the post info would be useful
