I've always been surprised there isn't a way to do this.
Perhaps the lack of such a feature is intentional? That is, to sort of "level the playing field" for posters and that the unintended effects from such a feature are greater than I realize?

But basically, some subreddits I subscribe I would like to filter out posts, or at least push down (or up) their display rank on my front page based on conditions set by user.

Some examples:

• only show (or prioritize) posts from r/MapPorn that have 500 upvotes.
  
• prioritize posts from r/EconHW or /r/AskEconomics that have <2 comments.
• show/prioritize posts from r/Worldnews that have >5000 votes unless the post is >6 hours old.
• hide posts from r/AskReddit with >1000 comments and post is >12 hours old.
  
• hide posts from all subreddits with titles containing the word "Republican" or "Democrat" or "Pancakes"
  

any thoughts on this? I wasn't sure if I should post this here or /r/ideasfortheadmins since I'm not sure how productive that sub is.
