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.
