Sure, "shitty content," is subjective. If I flag something and you don't think it should be flagged, upvote the comment. The system is designed that way. Points can have counterpoints and so on. A flag isn't the end-all be-all.

Just because your vote isn't worth much at the moment doesn't make you worthless. If no one bands together, this all crumbles. It's like saying that voting in an actual fair, transparent election is worthless because you're one person, you know what I'm saying?

Flagging is an option, and I'm not saying EVERYONE go do it, but be more conscious about its existence. Maybe smaller stake holders that want to flag/build themselves could just comment on a shit-post with "someone should flag this for X reason," and some other guy can swoop in and save the day?
