If this is possible, what is now the featured feed might be made up of recent posts that have yet to be rated, with a set time for exposure on the feed before they scroll off the page.
If a post is voted for, but still isn't rated quality, by the time it hits the bottom of the page, it gets shifted to trending.
If any post hits quality, it immediately shifts to quality.
So quality posts only appear in the quality, and discovery.
Edit: the automated way, the posts would only be sorted as "not voted for yet" so would show in the order they're posted. As posts are voted for they disappear from the feed - so when looking at this feed, they're either not so hot, or no one has seen them yet. Everyone who looks this feed curates. Counts as human I think It's more of a way to keep unseen posts in circulation longer.
