If I were concerned about maintaining an average, I'd be less likely to submit videos I wasn't sure of, like my Michael Douglas one </shameless self-promotion>, which has gotten 29 votes in 2.5 days. The goal of sifters should be to get stuff published, i.e. find lots of vids good enough to make the cut. Trying to maintain an average on top of that, I believe, would shift energy away from that goal and not benefit the Sift as much as the decreased volume would hurt it.

From another angle, what looming problem does this solve? Is anybody complaining about a lack of quality submissions? If so, the solution would be to up the number of votes required to get published, which is the point of a voting system in the first place.

That said, mods might find this stat useful internally so they could ask consistently successful how they go about finding good posts. I would not support publishing this stat, however.

Upvote because this reminds me of Michael Douglas in Basic Instinct
