Or flip it around - what if the next time Facebook sees you post 5 negative things in a row, it decides to positively skew what it shows you? i.e. trying to cheer up depressed people and stop suicide. It's creepy, eh?
Both sides are really creepy. A possible benefit of this experiment is gaining more insight into detecting whether people are happy or sad. Advertisers might soon be able to adapt their ads to a user's mood, thereby reinforcing the artificial connection between the company and the user. Users will feel like the brand really understands them.
