I have a perfectly lovely set of friends, who often post lovely things.

But when I think back to all the “long comments” and “spark conversation” type posts, they’re not lovely. They are politics or other things that spark FB’s equivalent of a flame war.

So my fear is that using those things to indicate these posts should be more prominent is going to be a tricky thing for them to get right.

Getting a computer to decide between “has lots of comments because it’s a fight” and “has lots of comments because it’s useful and interesting” is an interesting challenge.

A "Was that worth it?" button might help distinguish clickbait or angerbait from genuinely worthwhile and fulfilling information. Say you participated in a conversation on FB. When the conversation ends, you might get a notification from FB the next time to log in asking you whether it was good.

Or a news site could have a Was it worth it? button at the end of each story, to help identify clickbait or otherwise low-quality articles. Rather than measuring how many page views each journalist drives, they might measure how many satisfied readers that article had, and reward journalists who write high-quality articles.

That is a good statement of the problem. It seems like I've read about some pretty effective tone analysis for English, at least, that might be helpful.

Well, studies have said social media increases anxiety, I suppose because people usually post highlights of their lives, on average people's reaction to those posts is jealousy and feeling like "Why is my life shit?"...
