Cool tool.

Since I do a lot of manual curating, making searches more effective is an awesome idea.

Personally, I like to reward undervalued posts and helpful comments.

Also viewcount and followers might be a good field for filtering. New users barely get any upvotes because barely anyone noticed their posts, because they may not have followers yet.

I really feel happiest when rewarding new users. It can really make their day when a post suddenly earns them lots of new followers and rewards.
