Facebook posts as a whole have roughly the same quality of content whether a post has 1000 likes or it has no likes. A friend showing off photos of him in the Maldives, or a video of a cat dancing to EDM, how can you claim one is more valuable than the other? For the most part, Facebook is nothing more than a chatroom.

HN posts (and reddit posts in certain subreddits) genuinely do have a difference in quality, and that's where the value of upvotes/downvotes comes in.

Quality is in the eye of the beholder. Not everyone is looking for reasoned discourse, some really do want to see cat vids. And then there are plenty of good posts here that get passed by, or downvoted because of disagreement, and bad/misinformative posts that get upvoted. Social media popularity is to varying degrees a crapshoot.

I just don't see what Facebook should do here besides officially declare their platform Chatbook. And even if they did, how that would "help". Have you seen some chatrooms? Especially lightly moderated ones? Holy shit man.
