That's interesting, I know facebook has done some research on emotion/sentiment analysis on posts and comments. I could see a browser extension, a feature of a search engine or a content aggregator which analyses the emotional context of an article during indexing and displays an emoji describing the general tone of the article alongside an article's headline or link text. I might even go ahead and build a hacker news clone which tries to do this.

The funniest part will be to put the poop emoji next to a "fake news" or clickbait article.
