plugin idea: most appreciated/most likes (as a category)

i know others have requested this already; i just noticed a fairly simple way to do it.. and am thinking someone has most likely already done it and we missed it.

the idea is to have a page on the site for the most appreciated content.

i though that creating a category for 'best of site' and then assigning the items to that category would be enough.. but that requires manual interaction.. 
so then i thought of a plugin that can assign content to categories based on thresholds, such as 'liked by 25 people or more'.. 

that actually expands the idea to a useful concept of a general category assigner plugin, based on rules... which could include presets for best of site based on likes. or whatever you think of.

has anyone seen any plugins like this so far?
